What is the difference between strict and loose equality in JavaScript?

What is the difference between strict and loose equality in JavaScript?

In JavaScript, strict equality (===) checks for both value and type, while loose equality (==) converts types before checking.

Can you give me an example of both?

Sure! For strict equality: 1 === '1' is false. For loose equality: 1 == '1' is true because it converts the string to a number.

Why should I prefer strict equality?

Using strict equality helps avoid unexpected type coercion, making your code more predictable and easier to debug.

Are there any exceptions to this rule?

Yes, there are some edge cases, like comparing objects. Two different objects are never equal, even with loose equality.
