Understand immutable state immer.js

We changed objB's name and objA changed too. This is the mutable state. Indirectly modifying the values of other objects can cause code hazards in complex code logic. JSON. Parse (JSON. Stringify (objA)). My usual scheme is that the child node is modified, so the parent node, or parent node, is recreated...

The Implementation mechanism of IMmutable. Js

This article is the second in a series that delve deeper into immutable. In the last article, we studied the basic implementation principle of Immutable. Js persistent data structure, introduced its core data structure Vector Trie, and explored the bit partitioning mechanism. The fundamental reason for using bitpartitioning is to optimize speed, and for spatial optimization, Immutab...

Immutability for React

Immutability-helper is not immutable. IT is not a mutable function, but IT is not a mutable function. Immutability-helper is not a mutable function, IT is not a mutable function. I'm Su Nan, chief pit filling officer. But usually we make...

ES6 series arrow functions

Let's start by reviewing the basic syntax of arrow functions. This article focuses on comparing arrow functions with ordinary functions. The arrow function doesn't have this, so you need to find its value by looking in the scope chain. This means that if an arrow function is contained by a non-arrow function, this is bound to the nearest non-arrow function's this. Our requirement is to click a button to change the...
