Strings as Arrays

    //treating Strings like Arrays
    let log = console.log;

    let str = "Ragnar Lothbrok";
    
    // to split the string
    let arr = str.split("");    //splits string into an array
    let arr2 = Array.from(str); //splits any iterable and turns it into an array

    log(arr, arr2);

    // to target particular characters
    log(arr[0], arr2[1]);
    log(str[0], str[1]);
    log(str.charAt(0), str.charAt(1));

    // concat() - combine two arrays OR combine two strings
    str.concat("asdf");
    arr.concat(arr2);

    str.indexOf("g")      //2   
    str.lastIndexOf("g")  // 3
    arr.indexOf("R");     //0

    str.includes("R")     //true 
    arr.includes("R")     //true

    slice(begin, end)     // - extract / shallow copy of part of the array or string
    str.slice(1, 3)       // agn  
    arr.slice(1, 3)       // ["a", "g", "n"]
    
    // for...of needs and iterable, but both arrays and strings are iterable
    for (let char of str) {
      log(char);
    }

    for (let char of arr) {
