// ❌ Ugh, useless variable assignment
const [ignore, keep] = ['ignore', 'keep'];

// ✅ Good (blank space)
const [, keep] = ['ignore', 'keep'];

// ✅ Good ("_" communicates useless variable)
const [_ignore, keep] = ['ignore', 'keep'];

Comment

const url = 'www.samanthaming.com/tidbit.jpg';

// 1. Split string by "."
const array = url.split('.'); // [ 'www', 'samanthaming', 'com/tidbit', 'jpg' ]

// 2. Create only the variable we want
const [ , domain, ,type] = array;

// 3. Consuming the variable we created
const name = `${domain}.${type}`;
// 'samanthaming.jpg'
