How to use the useContext React hook
New Course Coming Soon:
Get Really Good at Git
Find out what the useContext React hook is useful for, and how to work with it!
Check out my React hooks introduction first, if you’re new to them.
One React hook I sometimes use is useContext
.
import React, { useContext } from 'react'
This hook is used in combination with the React Context API.
In particular, this hook allows us to get the current context value:
const value = useContext(MyContext)
which refers to the nearest <MyContext.Provider>
component.
Calling useContext
will also make sure the component rerenders when the context value changes.
I recommend you to read my Context API tutorial to know more about it.
Are you intimidated by Git? Can’t figure out merge vs
rebase? Are you afraid of screwing up something any time
you have to do something in Git? Do you rely on ChatGPT
or random people’s answer on StackOverflow to fix your
problems? Your coworkers are tired of explaining Git to
you all the time? Git is something we all need to use,
but few of us really master it. I created this course to
improve your Git (and GitHub) knowledge at a radical
level. A course that helps you feel less frustrated with
Git. Launching Summer 2024. Join the waiting list!
