How to Convert a RegExpStringIterator to An Array in JavaScript

When you are using String.matchAll in JavaScript, you get back a RegExpStringIterator, which you can loop through to get back the results.

// This will return RegExpStringIterator {}
const matches = 'paragraph'.matchAll(/graph/g);

for (const match of matches) {
    console.log(match);
}

To shorten things down, you can use array destructuring instead to instantly get back an array:

// This instead will return [Array(1)]
[...'paragraph'.matchAll(/graph/g)];
