When should I use equal vs identity operators in programming?

What’s the difference between equal and identity operators in JavaScript?

In JavaScript, the equal operator (==) checks for value equality, while the identity operator (===) checks for both value and type equality.

Can you give me an example of when to use each?

Sure! Use == when you want to compare values regardless of type, like 5 == '5'. Use === when you want to ensure both value and type match, like 5 === 5.

Are there any performance differences between them?

Yes, using === is generally faster because it doesn't perform type coercion, making it a better practice in most cases.

When should I avoid using the equal operator?

Avoid using == when you want to prevent unexpected results from type coercion, especially in complex comparisons.
