React Js Tutorial – React Component Lifecycle, State, Props #reactjs #javascript

  • Do you know what is meant by component lifecycle, state, props in React Js?
  • In this tutorial, you will learn about, – – The render method is the only required spec for the components.
  • If the component doesn’t need to render after state or props change then we can set it to false.
  • Every component has a state object and props object.
  • Let’s see the example of state and props below.

Learn about react lifecycle, state, props.Also, know the difference between state and props in this tutorial.Find out the complete react js tutorial here.

How to use React Lifecycle Methods » Andreas Reiterer

How to use #ReactJS Lifecycle Methods:  by @a_reiterer #JavaScript #Code

  • React components have several “lifecycle methods” that allow us to execute actions (e.g.: fetching data from a server) at particular times.
  • There are three particular stages in the lifecycle of a component, that are important for our lifecycle methods, which I will explain: – – When React creates an instance of a component and inserts it into the DOM (mounting), the following methods are called: – – If props or state…
  • That process is called unmounting and means that the following method is called: – – I hope I could give you a short overview of the life of a React component and the calling order of lifecycle methods.
  • Some people suggest to use it for doing some configuration of the root component that you can only do at runtime (e.g.: setting up a Firebase connection) – – Whenever this method is called, React has already rendered our component and put it into the DOM.
  • This means, it could be possible that the method returns false but React still decides to re-render the component.

Use React lifecycle methods to perform actions on mount, update and unmount of a component. Learn more about e.g. componentDidMount and when to use it

Typescript or Flow – Product at Home

#Typescript or #Flow: What’s your type?  #ReactJS

  • If you spend your days making 100-line apps or scripting stuff in a console, maybe adding types is not the thing for you.But if you’re working on bigger apps or libraries, spending a couple of hours to set up and learn the basics of TS or Flow will bring you…
  • You end up with a more robust and reliable code base.What really matters for you as a developer is the final outputI see a lot of guides, sometimes really good ones, focussed on the structural and implementation differences between TS and Flow — TS is a language, Flow isn’t etc. — but these aren’t the…
  • Let’s see what warnings TS and Flow are giving me:Typescript error messageFlow error messageTypescript clearly gives us the solution to fix the problem, whereas Flow just flags a type incompatibility.Errors on missing propsFor me this one is the biggest issues with Flow: Instead of having the error in the Title / component like…
  • Better yet, I could avoid this problem altogether in TS by taking advantage of with Atom and VS Code are fine, but from personal experience, Typescript remains faster than Flow, especially on large projects.So it looks like Typescript is clearly the best choice, or is it?Setup:If you have an existing project…
  • You’ll still need your unit and e2e tests to be sure that your app is running as expected.Both Flow and Typescript are awesome ❤ and I’m really happy that both of these solutions exist.

tldr; You’re not a machine. You just can’t catch all bugs and know your (and your team’s) code by heart and it’s not your job. So add static types! Ok, let’s clarify something here. If you spend your…
