Knowing how to program declaratively using pure functions is another key skill one should have, as it can completely change the way you code, for the better. With functional programming, you get to write the code purely through functions and avoid shared states, mutation of data, and side-effects. Due to the declarative nature of functional programming, the resultant code is more concise, predictable, and easier to test and alter. Also, because it is concise, the code can be executed faster, thereby improving the load times. Learning functional programming can be tough and time-consuming, but the advantages that come with it make it worth the time spent.
Of course, this list is not exhaustive and these are just four of many such skills that help you grow as a developer. Learning these techniques and knowing when to use them is of paramount importance. When used right, they’re sure to give the users of your website or app the best possible experience.
