There are various ways to empty a JavaScript array.
The easiest one is to set its length to 0:
const list = ['a', 'b', 'c']
list.length = 0
Another method mutates the original array reference, assigning an empty array to the original variable, so it requires using let instead of const:
let list = ['a', 'b', 'c']
list = []
