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

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

In JavaScript, equality (==) checks for value equality, while strict equality (===) checks for both value and type.

Can you give me an example of both?

Sure! For example, 5 == '5' is true because it converts the string to a number. But 5 === '5' is false because they are of different types.

Why is strict equality generally recommended?

Strict equality is recommended because it avoids unexpected type coercion, leading to more predictable and safer code.

Are there any exceptions to this rule?

Yes, there are some exceptions, like null == undefined being true, but null === undefined is false.
