Access object value using arr[index] as key

JavaScript
1

Hi, I’m just wondering why is the thirdconsole.log not working as the second one. Since char[1] is returning & why can’t I just pass it in so that I can access the value of & in the entities object?

  **Your code so far**

let entities = {
  "&" : "&",
  "<" : "&lt;",
  ">" : "gt;",
  '"': "&quot;",
  "'": "&apos;"
}
let char = Object.keys(entities)
console.log(char[1])                         // returns &
console.log(entities["&"])                  // &amp;
console.log(entities["char[1]"])            // undefined

These are not the same.
