I need to check if a name exists inside the array and return true if you find or false otherwise.

let names = ["Ana","João","Pedro","Maria"];

function hasName() {
  for (let i=0; i < names.length;i++) {
    if (names === "Pedro") {
      return true;
    }
  }
}

You’re comparing the whole set using names == "Pedro". You should only use one element names[i].

See below working:

let names = ["Ana","João","Pedro","Maria"]
console.log(hasName())

function hasName() {
  for (let i = 0; i < names.length; i++) {
    if (names[i] == "Pedro") {
      return true;
    }
  }
}
