JavaScript Comparison and Logical Operators

In this tutorial I’m going to learn how to use Comparison and logical operators in laravel. Comparison operators compare two values and give back a boolean value: either true or false. Comparison operators are used in decision making and loops.

OperatorDescriptionExample
==Equal to: true if the operands are equal5==5; //true
!=Not equal to: true if the operands are not equal5!=5; //false
===Strict equal to: true if the operands are equal and of the same type5==='5'; //false
!==Strict not equal to: true if the operands are equal but of different type or not equal at all5!=='5'; //true
>Greater than: true if the left operand is greater than the right operand3>2; //true
>=Greater than or equal to: true if the left operand is greater than or equal to the right operand3>=3; //true
<Less than: true if the left operand is less than the right operand3<2; //false
<=Less than or equal to: true if the left operand is less than or equal to the right operand2<=2; //true

Example 1: Equal to Operator

const a = 5, b = 2, c = 'hello';

console.log(a == 5);     // true
console.log(b == '2');   // true
console.log(c == 'Hello');  // false

Output:-

Not equal to !=

const a = 3,
b = 'hello';
// not equal operator
console.log(a != 2);
console.log(b != 'Hello');

Output:-

Strict equal to

const a = 2;
// strict equal operator
console.log(a === 2); // true
console.log(a === '2');

Output:-
