• Operators

    Logical operators in programming are like a set of tools that help us decide what to do depending on how things look. Logical operators tell the computer to do something based on how two different things compare.

      • Addition Arithmetic Operators

      • The addition operator returns the sum of two variables.

      • Javascript

        Example of addition operator in javascript.
        var age = 20;

console.log(age + 1); // 21

      • Subtraction Arithmetic Operators

      • The subtraction operator returns the difference of two variables.

      • Javascript

        Example of subtraction operator in javascript.
        var age = 20;

console.log(age - 2); // 18

      • Multiplication Arithmetic Operators

      • The multiplication operator returns the product of two variables.

      • Javascript

        Example of multiplication operator in javascript.
        var age = 20;

console.log(age * 3); // 60

      • Division Arithmetic Operators

      • The division operator returns the quotient of two variables.

      • Javascript

        Example of division operator in javascript.
        var age = 20;

console.log(age / 2); // 10

      • Modulus Arithmetic Operators

      • The modulus operator returns the remainder of two variables.

      • Javascript

        Example of modulus operator in javascript.
        var age = 20;

console.log(age % 9); // 2

      • Exponentiation Arithmetic Operators

      • The exponentiation operator returns the power of two variables.

      • Javascript

        Example of exponentiation operator in javascript.
        var age = 2;

console.log(age ** 3); // 8

      • Equal Comparison Operators

      • The equal operator checks if two variables are equal value.

      • Javascript

        Example of equal operator in javascript.
        var age = 20;

console.log(age == 20); // true

      • Equal Type Comparison Operators

      • The equal type operator checks if two variables are equal value and type.

      • Javascript

        Example of equal type operator in javascript.
        var age = '20';

console.log(age === '20'); // true

      • Not Equal Comparison Operators

      • The not-equal operator checks if two variables are not equal value.

      • Javascript

        Example of not-equal operator in javascript.
        var age = 20;

console.log(age != 18); // true

      • Not Equal Type Comparison Operators

      • The not-equal type operator checks if two variables are not equal value and type.

      • Javascript

        Example of not-equal type operator in javascript.
        var age = 20;

console.log(age !== '20'); // true

      • Greater Than Comparison Operators

      • The greater-than operator checks if the value of the first variable is greater than the second.

      • Javascript

        Example of greater-than operator in javascript.
        var age = 20;

console.log(age > 18); // true

      • Less Than Comparison Operators

      • The less-than operator checks if the value of the first variable is less than the second.

      • Javascript

        Example of less-than operator in javascript.
        var age = 20;

console.log(age < 21); // true

      • Greater Than or Equal Comparison Operators

      • The greater-than or equal-to operator checks if the value of the first variable is greater than or equal to the second.

      • Javascript

        Example of greater-than or equal-to operator in javascript.
        var age = 20;

console.log(age >= 20); // true

      • Less Than or Equal Comparison Operators

      • The less-than or equal-to operator checks if the value of the first variable is less than or equal to the second.

      • Javascript

        Example of less-than or equal-to operator in javascript.
        var age = 20;

console.log(age <= 20); // true
