How to get last array element in javascript

TIL (Today I Learned) that in JavaScript, there's a cool way to grab the last element of an array using the  at method. Instead of the traditional

const lastMember = members[members.length - 1]

which can sometimes feel clunky, now I can simply use

const lastMember = members.at(-1)

It's a nifty trick that makes code cleaner and more concise. Gotta love those little efficiency boosts in programming!
