Is it better to use if or else statements?

It leads to complicated designs, less readable code, and may be pain inducing to refactor. Nevertheless, If-Else has become the de facto solution for code branching — which does make sense. It’s one of the first things any aspiring developer is taught.

How to stop using IF-ELSE statements in code?

Applying the state pattern, you simply alter an objects behavior using specialized state objects instead of If-Else statements. Gone are the days with code looking like this below. You’ve certainly written more complicated branching before.

Which is the best way to write conditionals in JavaScript?
