60. When do we need to use non-strict mode?
Non-strict mode in JavaScript is the default mode in which JavaScript code is executed. In non-strict mode, the code runs with looser restrictions and allows some bad practices to work, which can lead to bugs and security issues. However, there are some cases where we might need to use non-strict mode:
Working with older code: If you are working with older legacy code that is not compatible with strict mode, you might need to use non-strict mode to run the code without errors.
Easier debugging: In some cases, when debugging a complex application, using non-strict mode can make it easier to locate and fix errors.
Library compatibility: If you are using third-party libraries that are not compatible with strict mode, you might need to use non-strict mode to use the library.
Incremental adaptation: If you want to start implementing strict mode in your code but need to do it incrementally, you might start by using non-strict mode in some parts of your application.
Note that while there are some cases where using non-strict mode might be necessary, it is generally recommended to use strict mode whenever possible to ensure code quality and security.
