Comparison Operators

In JavaScript, comparison operators are used to compare values and return a Boolean result (true or false) based on the comparison. There are several comparison operators in JavaScript, including:

• ==: Equal to (checks for value equality)
• ===: Strictly equal to (checks for value and type equality)
• !=: Not equal to (checks for value inequality)
• !==: Strictly not equal to (checks for value or type inequality)
• <: Less than
• >: Greater than
• <=: Less than or equal to
• >=: Greater than or equal to

Here are some examples of using comparison operators in JavaScript:

let a = 5;
let b = 10;
        
console.log(a < b); // true
console.log(a > b); // false
console.log(a <= b); // true
console.log(a >= b); // false
console.log(a == 5); // true
console.log(a === '5'); // false
console.log(a != 10); // true
console.log(a !== '5'); // true

In this example, we declare two variables, a and b, and then use various comparison operators to compare them and other values. The result of each comparison is a Boolean value (true or false), which is then logged to the console using console.log().
