To compare objects in JavaScript, the operators === and == are used. The distinction between the two operators is that while "==" compares values, "===" compares both values and types. It is also know as loose equality (==) and strict equality (===) operators.
console.log(5 === 5); // true
console.log("5" === 5); // false (different types)
console.log(5 === "5"); // false (different types)
console.log(true === true); // true
console.log(null === undefined); // false (different types)
console.log(5 == 5); // true
console.log("5" == 5); // true (converted string to number)
console.log(5 == "5"); // true (converted string to number)
console.log(true == 1); // true (converted boolean to number)
console.log(null == undefined); // true (special case)
With ===, you check both value and type equality explicitly, which is considered safer and less likely to lead to unexpected behavior. In contrast, == allows for greater flexibility because type coercion is performed, which can sometimes lead to unexpected outcomes.
