How does type inference work in JavaScript?

Can you explain how type inference works in JavaScript?

Sure! Type inference in JavaScript is the process where the engine automatically determines the type of a variable based on its value.

Does that mean I don't have to declare types explicitly?

Exactly! JavaScript is dynamically typed, so you can assign any type of value to a variable without declaring its type.

What happens if I assign a different type later?

If you assign a different type, JavaScript will adjust the variable's type accordingly. For example, you can start with a number and later assign a string.

Are there any downsides to type inference?

Yes, while it offers flexibility, it can lead to runtime errors if types are not managed carefully, making debugging harder.
