.===
(strict equal) operator returns true if the operands are equal and of the same type. The !==
(strict not equal) operator returns true if the operands are not equal and/or not of the same type. See "Comparison Operators" on page 635 and "Using the Equality Operators" on page 637.==
(equal) and !=
(not equal) operators reverts to the JavaScript 1.1 implementation. If the two operands are not of the same type, JavaScript attempts to convert the operands to an appropriate type for the comparison. See "Using the Equality Operators" on page 637.if(x = y)
. Previous JavaScript versions converted if(x = y)
to if(x == y)
, but 1.3 generates a runtime error. See "if...else" on page 623.undefined
or null
, including a Boolean object whose value is false, evaluates to true when passed to a conditional statement. See "Boolean" on page 51.Last Updated: 05/28/99 11:58:55
