Just experimenting with publishing a package

//Return the provided string with the first letter of each word capitalized. Make sure the rest of the word is in lower case
function titleCase(str){
  let lowercasearray = str.toLowerCase().split(" ")  //gives array 
 return(lowercasearray.map(value => value.replace(value.charAt(0),value.charAt(0).toUpperCase()))).join(" ")
}
console.log(titleCase("I'm a title case string"))

//change str to lowercase and split at (" ")
//map over it
//change value at charat(0) of each array to uppercase
//join


// function titleCase(str) {
//     return str.toLowerCase().replace(/(^|\s)\S/g, L => L.toUpperCase());
//   }

  //explanation
  //find all the non white space characters(\S)
  //at the beginning of the string(^) or(|) after any whitespace character(\s)
  //(g) search for other word pattern in the whole string
  //replace every word 1st character with uppercase
