Delay running next line of code when using ReactJS

Question

I want my code to wait 500 milliseconds before performing the next step.

I've used setTimeout but it doesn't work.

updateDisplay = arr => {
  setTimeout(function () {
    this.setState({ sortArray: arr });
  }, 500);
};

Chance `function() {` to an arrow function `() => {` so that you use the `this` in the surrounding scope, and not the one that gets bounded to your function expression — Nick Parsons, Dec 19 '20 at 01:32

Some simple incorrect syntax.

updateDisplay = (arr) => {
  setTimeout(() => this.setState({ sortArray: arr }), 500);
};
