// Let's create a new array of Programming Languages
const programmingLanguages = [
	'JS', 'Phython', 'PHP', 'JAVA', 'Kotlin'
];

// Declare an empty variable that will store the programmming languages
// in comma separated format
let languages = '';

// Use the for/of loop to iterate through the array of values
for (let singleLanguage of programmingLanguages) {
 	languages += singleLanguage + ', ';
}

// Upon printing to console, we will get the following output:
// JS, Phython, PHP, JAVA, Kotlin
console.log(languages);

// It is also possible to print out the index associated with the index elements using the entries() method.
// Loop through both index and element
for (let [index, singleLanguage] of programmingLanguages.entries()) {
    console.log(index, singleLanguage);
}

// Above will output the following:
// 0 "JS"
// 1 "Phython"
// 2 "PHP"
// 3 "JAVA"
// 4 "Kotlin"

// A string can also be iterated in the same way as an array.
// Let's assign a string to a variable
let hero = 'Super';

// Iterate through each index in the string
for (let heroCharacter of hero) {
    console.log(heroCharacter);
}

// Above will output the following:
// S
// u
// p
// e
// r
