If you're struggling with .reduce() then this one's for you. In it's simplest form it's an accumulator method to easily sum numbers: [1,2,3,4,5].reduce((prev,next) => prev+next); But that's just the beginning, and basic. Let's learn it properly... 💥⬇
💛 JavaScript explanation 💛 A basic use for reduce is to sum up all number elements of an array. This is how you can do it. ↓
💛 JavaScript explained 💛 Reduce is a pretty special array method because you can reimplement most array monad methods with it. This is how you implement map with reduce—a neat exercise to better understand what map does and how it works. ↓
💛 JavaScript explanation 💛 A basic use for reduce is to sum up all number elements of an array. This is how you can do it. ↓
💛 JavaScript explained 💛 You can use reduce to build your own functional pipe function. It's the functional equivalent of an object with chainable methods like an array with filter, map, flatMap, forEach, etc. Here is one possible implementation. ↓
reduce() is a very helpful function because it accomplishes two important tasks at once: writing unreadable code and showing off how smart you are
It took me a while to wrap my head around reduce in JavaScript (and it comes up a ton in technical interviews!). Here's a write up with some examples of how to use reduce in JavaScript: aboutmonica.com/blog/2020-03-2…
💡TIP: reduce can be used to perform multiple simultaneous calculations This example calculates the minimum, maximum, and average as an O(n) operation #javascript #nodejs #dev #code #programming #development
my rule for .reduce(): only use it when the result has the same type as the items and the reducer is associative, like .reduce((a, b) => a + b, 0) ✅ summing some numbers ✅ multiplying some numbers 🚫 building up a list or object 🚫 just about anything else (use a loop)
👩🏫 This is another video about the .reduce() method to help people understand what's happening to the accumulator, so you can see how it works, and what that initial value does! css-tricks.com/understanding-…
I wrote up a post to explain .reduce() for those who have a hard time grokking it. I made a few small videos to break stuff down. Here's video number one (for the text that accompanies it, check out the article below: css-tricks.com/understanding-…
