Currying Jan 24, 2019 - You would be right, but it is only the conceptual way of describing the operation to the language compiler or interpreter. The compiler or interpreter is free to take the first list and just overwrite the tenth position. The Javascript compiler is thus optimised to make pure functions efficient. Jan 15, 2020 - This year I had the chance to read this book Mastering Javascript Functional Programming by Federico Kereki. This is a book I personally recommend to whoever wants to have a deep understanding of Functional Programming concepts and their applications using Javascript.

Think of Functional Programming as it's own little farm or an ecosystem that doesn't rely on external elements and their result doesn't affect them either. It's just enjoying the vibes, minding their business. As a self-taught (and still learning) developer i often get confused by the terminology used to define concepts, but you don't have to! A programmer armed with a repertoire of fundamental functions and, more importantly, the knowledge on how to use them, is much more effective than one who starts from scratch. Unfortunately, a standard JavaScript environment comes with deplorably few essential functions, so we have to write ...

Functional Programming is a programming pattern or practice which is based on pure functions which focus on avoiding data sharing and mutations. Javascript is a multi-paradigm language that can be used as procedural, object-oriented, and functional according to our necessities and implementation. A functional program is a program that describes how to compute a function, in the mathematical sense of the word, that is, a contraption that always spits out the same output for the same input and does nothing else except for spitting out output.

Functional programming is a programming paradigm or style of programming that relies heavily on the use of pure and isolated functions. Just as you might have guessed from the name, the use of functions is the main component of functional programming. Moreover, all the functional programming correlates to mathematical functions in one way or the other. Functional programming supports first-class functions such as assigning functions to variables, returning and passing functions as returned values and arguments respectively, to/from other functions.
