Hi Ale,

I was paired with Marat, but he already did part of the Lab. He suggested to still do it together, but I was fine with some extra practise for myself. I had some help from Pool and Dani with iteration 3 and 5. I am happy with the outcomes, except for iteration 6 ('Find elements'). Jasmine says it's not returning true (both statements in Jasmine). Can you check my code and give me feedback on how to make it correctly? I can't find the bug in this one. Thank you so much!

Hey @elisejonkers
I'm happy you are happy!!! Well done with your solution!!!🙌

README INSTRUCTIONS: Declare a function named doesWordExist
that will take in an array of words as one argument
and a word to search for as the other.
Return true if the word exists in the array; otherwise, return false.

when invoked, this function needs to receive 2 arguments:

1. an array of strings, containg words
2. the word (a string) you wanna check if is inside
   EX: doesWordExist(wordsFind, "matter")

function doesWordExist(array, word) {
  // pass 2 parameters
  if (!array.length) {
    return null;
  }
  // const searchForThisWord = "";
  for (let i = 0; i < array.length; i++) {
    // check if one of the words inside the array is equal to the word we are looking for
    if (array[i] === word) {
      // it will stop the the loop, and return true.
      return true; 
    }
  }
  // all the other cases (no words matched) will return false
  return false;
}

the shortest and the cleanest:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/includes

function doesWordExist(wordsArr, word) {
   if (wordsArr.length === 0) {
     return null;
   } 
   return wordsArr.includes(word);
 }
