== (equality)

equality, comparison, ==

Availability

Flash Player 5.

Usage

    expression1 == expression2

Parameters

`expression1,expression2` A number, string, Boolean value, variable, object, array, or function.

Returns

Nothing.

Description

Operator (equality); tests two expressions for equality. The result is `true` if the expressions are equal.

The definition of equal depends on the data type of the parameter:

| Numbers and Boolean values are compared by value, and are considered equal if they have the same value.
| String expressions are equal if they have the same number of characters and the characters are identical.
| Variables, objects, arrays, and functions are compared by reference. Two variables are equal if they refer to the same object, array, or function. Two separate arrays are never considered equal, even if they have the same number of elements.

Example

The following example uses the `==` operator with an `if` statement:

    a = "David" , b = "David";
    if (a == b){
    	trace("David is David");
    }

Example

These examples show the results of operations that compare mixed types.

    x = "5"; y = "5";
    trace(x == y);
    // true

    x = "5"; y = "66";
    trace(x ==y);
    // false

    x = "chris"; y = "steve";
    trace (x == y);
    //false
