title: how to create a javascript function to return a string made of all the values in the array separated by +
body: <p>I am currently in an online bootcamp and I just started learning javascript and I am stuck on this simple question. Here is a copy of the question.</p>
  
  <p>Create a function named plusesEverywhere. This function should:</p>
  
  <p>take one argument, an array of at least two numbers.
  return a string made of all the values in the array separated by +.</p>
  
  <p>For example:</p>
  
  <p>plusesEverywhere([1,2,3]); // returns "1+2+3"
  plusesEverywhere([18,24]); // returns "18+24"</p>
  
  <p>I was thinking of using the splice method but not sure if that is the best approach. Thanks for helping!</p>
