If both operands point to the same object, then the equal operator returns true. There are four equality algorithms in JavaScript: IsLooselyEqual ( ) IsStrictlyEqual ( ): used by, , and case -matching.If both operands are objects, then the reference values are compared.If both operands are NaN, the equal operator returns false because, by rule, NaN is not equal to NaN.If either operand is NaN, the equal operator returns false and the not equal operator returns true.

In order for JavaScript to compare two different data types (for example, numbers and strings ), it must. Values of null and undefined cannot be converted into any other values for equality checking. Otherwise, the function will return Not Equal.Values of null and undefined are equal.If one operand is an object and the other is a number, attempt to convert the object to a number before checking for equality.If one operand is an object and the other is a string, attempt to convert the object to a string (using the toString() method) before checking for equality.If one operand is a string and the other is a number, attempt to convert the string into a number before checking for equality.If the value of two operands are not equal it returns. A value of false converts to 0 whereas a value of true converts to 1. Not equal is an comparison operator which is used to check the value of two operands are equal or not. If an operand is a Boolean value, convert it into a numeric value before checking for equality.When performing conversions, follow these basic rules: The not equal operator is the exclamation point followed by an equal sign (!=), and it returns true if operands are not equal.īoth operators do conversions in order to determine if two operands are equal. The equal operator in JavaScript is the double equal sign (=), and it returns true if both operands are equal. Equal and Not Equal : Relational Operators « Operators « JavaScript Tutorial
