Answers for "array.includes substring"

javascript string includes substring

var str = "We got a poop cleanup on isle 4.";
if(str.indexOf("poop") !== -1){
	alert("Not again");
}
//use indexOf (it returns position of substring or -1 if not found)

if array includes string

function droids(arr) {
  let result = 'These are not the droids you\'re looking for';
  for(let i=0; i<arr.length;i++) {
      if (arr[i] === 'Droids') {
      result = 'Found Droid';
    }
  }
  return result;
}

// Uncomment these to check your work! 
const starWars = ["Luke", "Finn", "Rey", "Kylo", "Droids"]
const thrones = ["Jon", "Danny", "Tyrion", "The Mountain", "Cersei"]
console.log(droids(starWars)) // should log: "Found Droids!"
console.log(droids(thrones)) // should log: "These are not the droi





//A simpler approach 

console.log(starWars.includes('Droids') ? 'Droid Found' : 'These are not the droids you\'re looking for');
console.log(thrones.includes('Droids') ? 'Droid Found' : 'These are not the droids you\'re looking for');
