JavaScript Comparisons

In JavaScript, comparisons are performed using comparison operators to evaluate conditions and make decisions in your code.

Here are the main comparison operators:

Equal to (==) and Strict Equal to (===)

Equal to (==): Checks if two values are equal, performing type coercion if necessary.

Strict Equal to (===): Checks if two values are equal without type coercion.

console.log(5 == '5'); // true (loose equality)
console.log(5 === '5'); // false (strict equality)

Not Equal to (!=) and Strict Not Equal to (!==)

Not Equal to (!=): Checks if two values are not equal, performing type coercion if necessary.

Strict Not Equal to (!==): Checks if two values are not equal without type coercion.

console.log(5 != '5'); // false (loose inequality)
console.log(5 !== '5'); // true (strict inequality)

Greater Than (>) and Less Than (<)

Greater Than (>): Checks if the value on the left is greater than the value on the right.

Less Than (<): Checks if the value on the left is less than the value on the right.

console.log(10 > 5); // true
console.log(5 < 10); // true

Greater Than or Equal to (>=) and Less Than or Equal to (<=)

Greater Than or Equal to (>=): Checks if the value on the left is greater than or equal to the value on the right.

Less Than or Equal to (<=): Checks if the value on the left is less than or equal to the value on the right.

console.log(10 >= 10); // true
console.log(5 <= 10); // true

These comparison operators return boolean values (true or false) based on the evaluation of the specified conditions.
