Typescript overuse of default parameter issue

	/**
	I created this gist to point out something I consider a bad practice that I've seen in typescript code:
	that is overuse of default parameters. The problem with overusing default parameters is that the default behavior
	of the function without args is completely implicit and requires the developer to reference the function definition and
	memorize whenever they are looking through the code.

	In the examples below I took some of our existing code that had such a function retrieveData where its behavior
	was hidden behind default parameters. I refactored it by using functions that are named something descriptive that
	then call retrieveData with the appropriate parameters. By providing a function with a descriptive name rather than
	letting parameter default it is much clearer what the code is doing when you are far away from the retrieveData
