The purpose of  proofreading is to review your work one final time to make sure it's error-free.

Explanation:

The proofreading involves the careful reading of the text by an expert, during which grammatical, stylistic and spelling errors are identified and corrected. It is focused on finding errors and making them into correct words or sentences.

It is very important to review your work due to finding all possible mistakes and be careful to correct them on time. Sometimes, you need someone to look over your work because you have read it multiple times and need someone who does not see it and is expert in grammatical, stylistic and spelling errors.
