Shulou(Shulou.com)06/02 Report--
This article mainly explains "what are the web programming skills", interested friends may wish to take a look. The method introduced in this paper is simple, fast and practical. Let Xiaobian take you to learn "what are the web programming skills"!
You should use functions like map, filter, and reduce instead of writing for or while loops. This is recommended because:
Loops make it easy to produce code side effects that turn code logic into spaghetti and clutter.
When you try to do more than one thing at a time, the cycle can cause you pain.
Functional programming prevents code from producing as many side effects as cold medicine. It forces you to do one thing at a time and is much more readable than looping.
Loops, like pointers, are a simple programming method. They're very useful for some critical code, but I think I'd say very few of us are working on graphics drivers.
Let's cut to the chase--here's a comparison of JavaScript programs. First, the old circular version:
const cats = ['Antonio', 'Squid', 'Tornado', 'Avocado', 'Barnacles', 'Abroteus']; const stringStartsWithA = x => x[0].toLowerCase() === 'a'; const catsWhoseNameStartsWithA = []; for (let i = 0; i
< cats.length; i++) { if (stringStartsWithA(cats[i])) { catsWhoseNameStartsWithA.push(cats[i]); } } console.log(catsWhoseNameStartsWithA); // Output: // ["Antonio", "Avocado", "Abroteus"] 下面是新式的函数式编程: const cats = ['Antonio', 'Squid', 'Tornado', 'Avocado', 'Barnacles', 'Abroteus']; const stringStartsWithA = x =>x[0].toLowerCase() === 'a'; const catsWhoseNameStartsWithA = cats.filter(stringStartsWithA); console.log(catsWhoseNameStartsWithA); // Output: // ["Antonio", "Avocado", "Abroteus"]
Of course, this is a simple example, and probably a good use case for filters. Still, we turned 5 lines of messy code into... 0 lines? In *** examples, we have used a line of code to declare arrays.
At this point, I believe that everyone has a deeper understanding of "what are the web programming skills", may wish to actually operate it! Here is the website, more related content can enter the relevant channels for inquiry, pay attention to us, continue to learn!
