Basic Hooks!

As much as I would love to chat about how cool Dustin Hoffman’s shiny hand toothpick looks, we are not going to chat about the movie Hook. We are here to talk very briefly about React Hooks! As I am learning React, I have come across a lot of code written with Hooks. Since I didn’t understand it at first, here‘s my attempt to explain… Hooks.

Note: If you have questions on React or Hooks, please check out the great documents the React team has put together here and here. I am just going to cover two examples of the basics.

What is a React Hook? Introduced on February 6, 2019, Hooks are a way of creating components without creating a class! Hooks let you manipulate state and other React features of the component lifecycle from functional components.

But why should I care? If you are familiar with building out big components you may find yourself running into difficulty refactoring or you may have paralleled or duplicated logic, or worse heavily nested components referred to as wrapper hell.

Hooks help us stay DRY and makes our code more organized and reusable by breaking down reusable code into smaller functions.

React hooks - Giới thiệu tổng quát về Hooks

React hooks ra đời đã giúp functional component trở nên powerful hơn bao giờ hết! 😍Trước đây khi cần dùng đến các tính năng của React như state, life cycle thì mình bắt buộc phải dùng class component. Nhưng giờ thì đã khác, có hooks, functional component như hổ mọc thêm cánh, có thể xử lý được state, life cycle và những thứ khác của React một cách êm đềm.

Cùng mình xem hết videos để khám phá những điều thú vị từ React hooks nhé! 😉

Hooks, Hooks, Hooks!

Prior to 2018, React, an already powerful and widely-used javascript library for building user interfaces, had 3 cumbersome issues:

  1. Reusing logic: in order to to create dynamic interfaces where state is manipulated, logic was constantly being copied for seemingly simple tasks like updating the state from a form field. This often would lead to complicated and bloated data structures.
  2. Giant components: logic often times gets split amongst various lifecycle. methods in order to keep your application working.
  3. Confusing classes: invariably with reused logic and oversized components, our classes themselves can become confusing for both user and the machine.

As Dan Abramov of the React Dev team describes it, these are really three separate issues, but rather systems of the same problem: before 2018, _React did not provide a stateful primitive that is simpler than incorporating a class component and its associated logic. _At one point, React used mixins to pseudo-resolve this issue, but that ultimately created more problems that it solved.

How did the React team resolve this seemingly singular, but hugely impactful inconvenience? Hooks to the rescue.
