When JavaScript code is run, the command ‘use strict’ is used to activate the strict mode, which automates tighter parsing and error handling. This enables us to use a limited version of JavaScript. It allows us to examine the JavaScript code and throw more errors, as well as resolve any bugs that may occur in future JavaScript versions.
The following are some of the benefits of using strict:
- Removes certain obnoxious Javascript syntactic characteristics.
- Removes certain inconsistencies in the code’s functioning.
- Ensures the security of the code running
- Improves compiler efficiency
