Finding Unused Javascript Functions

Question

JavaScript

The task is this - there are several js files stuffed with functions. The functions are quite heterogeneous, just piled together.

They can be used from other js modules, they can be written directly in html templates, or they can also appear in php sources.

You need to find functions that are definitely not called anywhere.

In fact, the task is simple - parse the specified files for function definitions, then parse another bunch of files for names. Issue a list of those that were not found or were found but very few.

In principle, it is not difficult to write it yourself, but what if there is already such a tool?

Answer 1

phpStorm IDE www.jetbrains.com/phpstorm/ but it's a development environment

Answer 2

The automatic method will not give one hundred percent certainty.

obj['method_' + 'name']();
