How can I avoid type coercion issues in JavaScript?

How can I avoid type coercion issues in JavaScript?

To avoid type coercion issues, always use strict equality (===) instead of loose equality (==). This ensures that both value and type must match.

What are some common examples of type coercion in JavaScript?

Common examples include adding a number to a string, which converts the number to a string, or comparing a number to a boolean, which can lead to unexpected results.

How can I check the type of a variable before performing operations?

You can use the typeof operator to check the type of a variable. For example, typeof myVar will return the type of myVar.

Are there any tools or libraries to help with type checking?

Yes, TypeScript is a popular superset of JavaScript that adds static type checking, helping to catch type coercion issues at compile time.
