var array = [400, 4000, 400, 400, 4000];

How can I get the index of the first element with value greater than 400?

Answer 1

You can use findIndex here

check this snippet

var array = [400, 4000, 400, 400, 4000];
var index=array.findIndex(function(number) {
  return number > 400;
});
console.log(index);
