An operator is capable of manipulating(mathematical and logical computations) a certain value or operand. There are various operators supported by JavaScript as below,. Arithmetic operators are used to perform mathematical operations between numeric operands. JavaScript provides comparison operators that compare two operands and return a boolean value true or false. The logical operators are used to combine two or more conditions. 1. && - is known as AND operator. It checks whether two operands are non-zero or not (0, false, undefined, null or "" are considered as zero). It returns 1 if they are non-zero; otherwise, returns 0. 2. || - is known as OR operator. It checks whether any one of the two operands is non-zero or not (0, false, undefined, null or "" is considered as zero). It returns 1 if any one of of them is non-zero; otherwise, returns 0. 3. ! - is known as NOT operator. It reverses the boolean result of the operand (or condition). !false returns true, and !true returns false. The assignment operators to assign values to variables with less key strokes.
