/* toTitleCase
Write a function that will capitalize every word in a sentence.

Example Output: "Everything, Everywhere, All At Once"

First, write a function that takes in one word and 
capitalizes the first letter of that word.

Example Input: "scrimba"
Example Output: "Scrimba"

Hint: Trying using slice() and .toUpperCase()

Now write a function that capitalizes every word in a sentence. 
How can you reuse the function you just wrote?

// This is how i solved it ->

// let str = "hello world! i am a developer";

// function capitalize(str){
//     let str1 = str.split("");
//     str1[0] = str1[0].toUpperCase();
//     for(let i = 1; i < str1.length; i++){
//         if(str1[i] === " "){
//             str1[i + 1] = str1[i + 1].toUpperCase();
//         }
//     }
//     return str1.join("");
// }

// console.log(capitalize(str));
