All Operators OPERATORS: == != === !== > >= < <= A comparison operator compares two operands and returns a Boolean value (true or false) as to the validity of the comparison. Operands can be of numeric or string type.  == This is the equal operator and returns a boolean true if both the operands are equal. JavaScript will attempt to convert different data types to the same type in order to make the comparison. Assuming 'a' to be 2 and 'b' to be 4, the following examples will return a value of true:   a == 2 a == "2" 2 == '2'  !=   This is the not equal operator which returns a Boolean true if both the operands are not equal. Javascript attempts to convert different data types to the same type before making the comparison. The following examples return a Boolean true:   a != b a != 4 a != "2"  === This is the strict equal operator and only returns a Boolean true if both the operands are equal and of the same type. These next examples return true:   a === 2 b === 4  !==   This is the strict not equal operator and only returns a value of true if both the operands are not equal and/or not of the same type. The following examples return a Boolean true:   a !== b a !== "2" 4 !== '4'  >   This is the greater than operator and returns a value of true if the left operand is greater than the right.:   a > 1 b > a  >= This is the greater than or equal operator, which returns true if the first operand is greater than or equal to the second. The following examples return true:   a >= 1 a >= 2 b >= a  <   This is the less than operator and returns true if the left operand is less than the right:   a < 3 a < b  <= This is the less than or equal operator and returns true if the first operand is less than or equal to the second. These next examples all return true:   a <= 2 a <= 3 a <= b Copyright 1999-2001 by Infinite Software Solutions, Inc. All rights reserved. Trademark Information
