For...of Loop Refactoring

for...of loops over iterable objects, for example arrays or strings.

The for...of loop is easier to read than indexed for loops and can replace them in many cases.

For example,

for (let i = 0; i < elements.length; i++) {
    const element = elements[i];
    console.log(element);
}

can be replaced by

for (const element of elements) {
    console.log(element);
}

For..of loops have been introduced with ES6. Learn More: for...of (MDN)

P42 now supports converting regular for-loops over arrays with index variables into more concise for-of loops. The refactoring is available on the playground and for all repositories.
