In JavaScript, operators are symbols or keywords used to perform operations on one or more values (operands). There are several types of operators in JavaScript, including:
1. Arithmetic operators :
Used to perform mathematical operations on operands. Examples include + (addition), - (subtraction), * (multiplication), / (division), % (modulus), and ++ (increment) and -- (decrement).
2.Comparison operators :
Used to compare two values and return a boolean value (true or false). Examples include == (equal to), != (not equal to), === (strictly equal to), !== (strictly not equal to), < (less than), > (greater than), <= (less than or equal to), and >= (greater than or equal to).
3.Logical operators :
Used to perform logical operations on boolean values. Examples include && (logical AND), || (logical OR), and ! (logical NOT).
4.Assignment operators :
Used to assign values to variables or modify the values of variables. Examples include = (assignment), += (addition assignment), -= (subtraction assignment), *= (multiplication assignment), /= (division assignment), %= (modulus assignment), <<= (left shift assignment), >>= (right shift assignment), &= (bitwise AND assignment), ^= (bitwise XOR assignment), and |= (bitwise OR assignment).
5.Bitwise operators :
Used to perform bitwise operations on operands. Examples include & (bitwise AND), | (bitwise OR), ^ (bitwise XOR), ~ (bitwise NOT), << (left shift), and >> (right shift).
6.Conditional (ternary) operator :
Used to assign a value to a variable based on a condition. The syntax is condition ? value1 : value2. If the condition is true, value1 is assigned to the variable. Otherwise, value2 is assigned.
7.typeof operator :
Used to determine the type of a value. The typeof operator returns a string indicating the data type of the operand.
