I have a project that requires the usage of 2 defined classes "Function" and "Type", which are both also defined by the framework used in the project "Angular". How do I specify that my versions of "Function" and "Type" are used, instead of Angular's version? I can't change the names to something else, because the entire project needs those names specifically. It's a tricky situation mainly because the subject of the project is "programming". Does anyone have an idea of how to make sure that my versions of "Function" and "Type" are used?
