Comparison Operators in JavaScript

Comparison operators allow us to compare values and obtain a boolean result (`true` or `false`) according to the relationship between the values.

These operators allow us to compare two values and determine if they are equal, different, greater, or less than, and are essential for evaluating expressions and making decisions.

The arithmetic operators of JavaScript are:

OperatorNameDescription
`==`EqualityCompares if two values are equal
`===`Strict equalityCompares if two values and their type are identical
`!=`InequalityCompares if two values are different
`!==`Strict inequalityCompares if two values and their type are not identical
`>`Greater thanChecks if one value is greater than another
`<`Less thanChecks if one value is less than another
`>=`Greater than or equalChecks if one value is greater than or equal
`<=`Less than or equalChecks if one value is less than or equal

List of comparison operators

Equality (==)

The equality operator `==` compares two values and returns `true` if they are equal, `false` if they are different. This operator does not take into account the data type.

``````5 == 5; // true
5 == '5'; // true, comparison does not take into account the type``````

Strict Equality (===)

The strict equality operator `===` compares two values and returns `true` if they are equal and of the same type, `false` if they are different.

``````5 === 5; // true
5 === '5'; // false, the types are different``````

Inequality (!=)

The inequality operator `!=` compares two values and returns `true` if they are different, `false` if they are equal. This operator does not take into account the data type.

``````5 != 3; // true
5 != '5'; // false, comparison does not take into account the type``````

Strict Inequality (!==)

The strict inequality operator `!==` compares two values and returns `true` if they are different or of different types, `false` if they are equal and of the same type.

``````5 !== 3; // true
5 !== '5'; // true, the types are different``````

Greater than (>), Greater than or equal (>=)

These operators compare two numerical values and return `true` if the first value is greater (or greater than or equal) than the second, `false` if it is not.

``````5 > 3; // true
5 >= 5; // true``````

Less than (<), Less than or equal (<=)

These operators compare two numerical values and return `true` if the first value is less (or less than or equal) than the second, `false` if it is not.

``````5 < 10; // true
5 <= 5; // true``````
