Capitalize the first letter of every word

Question

I want to use a javascript function to capitalize the first letter of every word

eg:

THIS IS A TEST ---> This Is A Test
this is a TEST ---> Th         


        

Answer 1

This is a simple solution that breaks down the sentence into an array, then loops through the array creating a new array with the capitalized words.

 function capitalize(str){

  var strArr = str.split(" ");
  var newArr = [];

  for(var i = 0 ; i < strArr.length ; i++ ){

    var FirstLetter = strArr[i].charAt(0).toUpperCase();
    var restOfWord = strArr[i].slice(1);

    newArr[i] = FirstLetter + restOfWord;

  }

  return newArr.join(' ');

}
