VisualizaçõesIs there anyway to get rid of binding `this` to `Component` functions in react?
This is what I do when I want to make this of my class functions bind to the class (component) instance. Is there any easier/more proper way to do this in React?
class App extends Component {
state = {
currentSection: 1,
message :{text:''}
};
constructor(props) {
super(props);
this.prevSection = this.prevSection.bind(this);
this.nextSection = this.nextSection.bind(this);
this.mobileChanged = this.mobileChanged.bind(this);
}
}

You could use arrow function instead of class method
With arrow function, there will be no this context so you won't have to bind it
class App extends Component {
state = {
currentSection: 1,
message: { text: '' },
};
prevSection = () => {}
nextSection = () => {}
mobileChanged = () => {}
}

If I recall correctly, if you change:
function nextSection() {...}
to
const nextSection = () => {...}
After this change, you can remove this and the bind
Please let me know if your component will remain as functional like it was before. I'm not sure if it this will change the behaviour.
