Javascript

JavaScript has two operators for checking equality. One is == (equality operator or loose equality operator) and the other one is === (strict equality operator). Both of these operators check the value of operands for equality. But, the difference between == & === is that the == does a type conversion before checking for equality. Similarly, we have two, not equal operators != and !==

Comparison Operators or Relational operators compares the values of the two operand . The comparison operators are less than <, less than or equal <=, greater than >, greater than equal >=, equal (== & ===) & not equal ( != & !==). All comparison operators return true or false.

We use the increment & decrement operators to increase or decrease the value of the variable by one. JavaScript uses the ++ (increment) & — (decrement) to denote them. We can either prefix or Postfix these operators.

The unary plus operator (+) precedes its operand and converts it into a number. If it fails to convert the operand into a number, then it returns NaN. The unary (-) operator converts the operand into a number and negates it.

The JavaScript arithmetic operators take numerical values as their left & right operands, perform the arithmetic operation, and return a numerical value. The JavaScript supports all the arithmetic operators like addition (+), subtraction (-), multiplication (*), division (/), etc. Note that all the numbers in JavaScript are represented as IEEE 754 floating-point numbers and use floating-point arithmetic.
