// Example Whiteboard Problem: Find the number of times a name, "bob", repeats in a sentence. 

// input : string
// output : number
// example string: 'Once upon a time Bob had a farm. Bob was happy. bobbity bon';

// Attempt 1

const sentence = 'Once upon a time Bob had a farm. Bob was happy. bobbity bon';

const findRepeatingWord = (str) => {
  let keyword = 'bob';
  let count = 0;

// loop through the string

  str.split(' ');

for (let i = 0; i < str.length; i++){

// find the matching words
   if (i == keyword) {

// increment count
   count++;
   }
}
 return count;
}

// Attempt 2
const findRepeatingWord = (string) => {
  string.toLowerCase();
  string.split();
  let count = 0;
  for (let word in string)
    if( word.includes('bob', 0)){
      return count++;
      }
    return count;
  }
  
// Attempt 3

const findRepeatingWord = (str) => {
  str.match(keyword/gi).length;
}
