Calling a function basis on the input value changes in JavaScript [closed]-CodePudding

I have one HTML input field ,I want when a user start typing in this field functionA() should be called ,and wait for 10seconds ,and after 10seconds if user is still typing then again functionA() should be called ,otherwise functionB should be called. How can I achieve this in JavaScript

});

if user coninuesly typing then it will call functionA and if user pause typing for 10 seconds and start typing again. it will go to functionB

let timer = null;
let timeOut = false;
const onChange = (e) => {
  if(timeOut) {
    functionB(e)
    return;
  } else {
    clearTimeout(timer)
    timer = setTimeout(()=> timeOut = true, 10000)
    functionA(e)
  } 
}
const functionA = (e) => {
  console.log('A', e)
}

const functionB = (e) => {
  console.log('B', e)
}

<input onKeyUp="onChange(this.value)"/>
