JavaScript filtering array full of objects

Question

I am having trouble with some basic javascript. I want this function to return an array of all objects within the given array that have the name "Ray" assigned to name. I can't get the push part to work.

  const people = [{name: "Jack", age: 30}, {name: "Ray", age: 32}, {name: "Anna", age: 28}]; 
  
function findRay(arr) {
  let response = []; 
  for(let i = 0; i < arr.length; i++) {
    if(arr[i].name === "Ray") {
      response.push(arr[i]); 
    }
  }
  return response;
}
  
console.log(findRay(people));

Concur that it works. What browser are you using? Try changing const people = [......] to var people = [......] — terpinmd, Aug 03 '17 at 19:08
I'm on Chrome. Also tried in Repl.it. This code does not work. — J Seabolt, Aug 03 '17 at 19:11

Well, it does: https://repl.it/JwCl Maybe explain what do you mean with "does not work"? — yuriy636, Aug 03 '17 at 19:13
I forgot to add console.log to my local code... silly mistake. Thank you for pointing out that this version worked. — J Seabolt, Aug 03 '17 at 19:17

While not exactly what you were looking for, this is a good use case for filter(). So you could do something like const findRay = arr => arr.filter(person => person.name === "Ray").
