Introduction
+
+

+ JavaScript is a cross-platform, object-oriented scripting language. It is a small and lightweight + language. Inside a host environment (for example, a web browser), JavaScript can be connected to the + objects of its environment to provide programmatic control over them. +

+ +

+ JavaScript contains a standard library of objects, such as Array, Date, and Math, and a core set of + language elements such as operators, control structures, and statements. Core JavaScript can be + extended for a variety of purposes by supplementing it with additional objects; for example: +

+
    +
  • + Client-side JavaScript extends the core language by supplying objects to control a browser and + its Document Object Model (DOM). For example, client-side extensions allow an application to + place elements on an HTML form and respond to user events such as mouse clicks, form input, and + page navigation. +
  • +
  • + Server-side JavaScript extends the core language by supplying objects relevant to running + JavaScript on a server. For example, server-side extensions allow an application to communicate + with a database, provide continuity of information from one invocation to another of the + application, or perform file manipulations on a server. +

What you should already know
+
+

This guide assumes you have the following basic background:

+ +
    +
  • + A general understanding of the Internet and the World Wide Web (WWW). +
  • +
  • + Good working knowledge of HyperText Markup Language (HTML). +
  • +
  • + Some programming experience. If you are new to programming, try one of the tutorials linked on + the main page about JavaScript. +
  • +
+
+
+
+
JavaScript and Java
+
+

+ JavaScript and Java are similar in some ways but fundamentally different in some others. The + JavaScript language resembles Java but does not have Java's static typing and strong type checking. + JavaScript follows most Java expression syntax, naming conventions and basic control-flow constructs + which was the reason why it was renamed from LiveScript to JavaScript. +

+ +

+ In contrast to Java's compile-time system of classes built by + declarations, JavaScript supports a runtime system based on a small + number of data types representing numeric, Boolean, and string values. + JavaScript has a prototype-based object model instead of the more common class-based object model. + The prototype-based model provides dynamic inheritance; that is, what is inherited can vary for + individual objects. + JavaScript also supports functions without any special declarative + requirements. Functions can be properties of objects, executing as + loosely typed methods. +

+

+ JavaScript is a very free-form language compared to Java. You do not + have to declare all variables, classes, and methods. You do not have to be concerned with whether + methods are public, private, or protected, and you do not have to implement interfaces. Variables, + parameters, and function return types are not explicitly typed. +

+
+
+
+
Hello world
+
+ To get started with writing JavaScript, open the Scratchpad and write your first "Hello world" + JavaScript code: + +
+function greetMe(yourName) 
+{ 
+    alert("Hello " + yourName); 
+}
+
+greetMe("World");
+
+
+
+
+
Variables
+

+ You use variables as symbolic names for values in your application. The + names of variables, called identifiers, conform to certain rules. +

+

+ A JavaScript identifier must start with a letter, underscore (_), or + dollar sign ($); subsequent characters can also be digits (0-9). Because + JavaScript is case sensitive, letters include the characters "A" through + "Z" (uppercase) and the characters "a" through "z" (lowercase). +

+

+ You can use ISO 8859-1 or Unicode letters such as å and ü in identifiers. + You can also use the Unicode escape sequences as characters in + identifiers. Some examples of legal names are Number_hits, temp99, and + _name. +

+
+
+
Declaring variables
+
+ You can declare a variable in three ways: +

+ With the keyword var. For example, var x = 42. This syntax can be + used to declare both local and global variables. +

+

+ By simply assigning it a value. For example, x = 42. This always + declares a global variable. It generates a strict JavaScript + warning. You shouldn't use this variant. +

+

+ With the keyword let. For example, let y = 13. This syntax + can be used to declare a block scope local variable. See Variable scope + below. +

+
+
+
+
Variable scope
+
+

+ When you declare a variable outside of any function, it is called a + global variable, because it is available to any other code in the + current document. When you declare a variable within a function, it is called a local variable, + because it is available only within that + function. +

+ +

+ JavaScript before ECMAScript 2015 does not have block statement scope; rather, a variable declared + within a block is local to the function (or global scope) that the block resides within. For example + the following code will log 5, because the scope of x is the function (or global context) within + which x is declared, not the block, which in this case is an if statement. +

+
if (true) { var x = 5; } console.log(x); // 5
+

+ This behavior changes, when using the let declaration introduced in + ECMAScript 2015. +

+ +
+if (true) { let y = 5; } 
+console.log(y);
+// ReferenceError: y is not defined
+
+
+
+
+
Global variables
+
+

+ Global variables are in fact properties of the global object. In web + pages the global object is window, so you can set and access global + variables using the window.variable syntax. +

+ +

+ Consequently, you can access global variables declared in one window or frame from another window or + frame by specifying the window or frame name. For example, if a variable called phoneNumber is + declared in a document, you can refer to this variable from an iframe as parent.phoneNumber. +

+
+
+
+
Constants
+
+

+ You can create a read-only, named constant with the const keyword. The syntax of a constant + identifier is the same as for a variable identifier: it must start with a letter, underscore or + dollar sign and can contain alphabetic, numeric, or underscore characters. +

+ +
const PI = 3.14;
+

+ A constant cannot change value through assignment or be re-declared while the script is running. It + has to be initialized to a value. +

+ +

+ The scope rules for constants are the same as those for let block scope variables. If the const + keyword is omitted, the identifier is assumed to represent a variable. +

+ +

+ You cannot declare a constant with the same name as a function or variable in the same scope. For + example: +

+ +
+// THIS WILL CAUSE AN ERROR 
+function f() {}; const f = 5; 
+// THIS WILL CAUSE AN ERROR ALSO 
+function f() { const g = 5; var g;//statements}
+
+ + However, object attributes are not protected, so the following statement + is executed without problems. + +
const MY_OBJECT = {"key": "value"}; MY_OBJECT.key = "otherValue";
+
+
+
+
Data types
+
+

The latest ECMAScript standard defines seven data types:

+
    +
  • +

    Six data types that are primitives:

    +
      +
    • Boolean. true and false.
    • +
    • + null. A special keyword denoting a null value. Because JavaScript is + case-sensitive, null is not the same as Null, NULL, or any other variant. +
    • +
    • + undefined. A top-level property whose value is undefined. +
    • +
    • Number. 42 or 3.14159.
    • +
    • String. "Howdy"
    • +
    • + Symbol (new in ECMAScript 2015). A data type whose instances are unique and + immutable. +
    • +
    +
  • + +
  • and Object
  • +
+ Although these data types are a relatively small amount, they enable you + to perform useful functions with your applications. Objects and functions + are the other fundamental elements in the language. You can think of + objects as named containers for values, and functions as procedures that + your application can perform. +
+
+
+
if...else statement
+
+ Use the if statement to execute a statement if a logical condition is + true. Use the optional else clause to execute a statement if the condition is false. An if statement + looks as follows: + +
if (condition) { statement_1; } else { statement_2; }
+ + condition can be any expression that evaluates to true or false. See + Boolean for an explanation of what evaluates to true and false. If + condition evaluates to true, statement_1 is executed; otherwise, + statement_2 is executed. statement_1 and statement_2 can be any statement, including further nested if + statements. +

+ You may also compound the statements using else if to have multiple + conditions tested in sequence, as follows: +

+ +
+if (condition_1) { statement_1; }
+else if (condition_2) { statement_2; }
+else if (condition_n) { statement_n; }
+else { statement_last; }
+
+ + In the case of multiple conditions only the first logical condition which evaluates to true will be + executed. To execute multiple statements, group them within a block statement ({ ... }) . In general, + it's good practice to always use block statements, especially when nesting if statements: + +
+if (condition) { 
+    statement_1_runs_if_condition_is_true;
+    statement_2_runs_if_condition_is_true; 
+} else {
+    statement_3_runs_if_condition_is_false;
+    statement_4_runs_if_condition_is_false; 
+}
+
+ + It is advisable to not use simple assignments in a conditional expression, because the assignment can be + confused with equality when glancing over the code. For example, do not use the following code: + +
if (x = y) { /* statements here */ }
+ + If you need to use an assignment in a conditional expression, a common practice is to put additional + parentheses around the assignment. For example: + +
if ((x = y)) { /* statements here */ }
+
+
+
+
while statement
+
+ A while statement executes its statements as long as a specified condition evaluates to true. A while + statement looks as follows: + +
while (condition) statement
+ +

+ If the condition becomes false, statement within the loop stops executing and control passes to the + statement following the loop. +

+ +

+ The condition test occurs before statement in the loop is executed. If the condition returns true, + statement is executed and the condition is tested again. If the condition returns false, execution + stops and control is passed to the statement following while. +

+ +

+ To execute multiple statements, use a block statement ({ ... }) to group those statements. +

+ + Example: + +

+ The following while loop iterates as long as n is less than three: +

+ +
var n = 0; var x = 0; while (n < 3) { n++; x += n; }
+

+ With each iteration, the loop increments n and adds that value to x. + Therefore, x and n take on the following values: +

+ +
    +
  • After the first pass: n = 1 and x = 1
  • +
  • After the second pass: n = 2 and x = 3
  • +
  • After the third pass: n = 3 and x = 6
  • +
+

+ After completing the third pass, the condition n < 3 is no longer + true, so the loop terminates. +

+
+
+
+
Function declarations
+
+ A function definition (also called a function declaration, or function + statement) consists of the function keyword, followed by: + +
    +
  • The name of the function.
  • +
  • + A list of arguments to the function, enclosed in parentheses and + separated by commas. +
  • +
  • + The JavaScript statements that define the function, enclosed in curly brackets, { }. +
  • +
+

+ For example, the following code defines a simple function named square: +

+ +
function square(number) { return number * number; }
+

+ The function square takes one argument, called number. The function + consists of one statement that says to return the argument of the + function (that is, number) multiplied by itself. The return statement specifies the value returned + by the function. +

+
return number * number;
+

+ Primitive parameters (such as a number) are passed to functions by + value; the value is passed to the function, but if the function changes the value of the parameter, + this change is not reflected globally or in the calling function. +
