How can I debug type coercion issues in JavaScript?

How can I debug type coercion issues in JavaScript?

Type coercion issues often arise when JavaScript automatically converts types. You can debug these by using strict equality (===) to check types, and by using console.log to inspect values before operations.

Can you give me an example of a type coercion issue?

Sure! For instance, if you compare a string and a number like this: '5' == 5, JavaScript will coerce the string to a number, resulting in true. But using '5' === 5 will return false because the types are different.

What tools can help me identify these issues?

You can use browser developer tools, like the console for logging, and linters like ESLint to catch potential type coercion issues before they happen.

Are there best practices to avoid type coercion problems?

Yes! Always use strict equality (===), avoid implicit type conversions, and be mindful of operations involving different types.
