Script Preparation code:

var str = 'player/attack-bottom/1'

Tests:

lastIndexOf
const idx = str.lastIndexOf('/') const r1 = str.substring(0, idx) const r2 = str.substring(idx + 1, str.length)
split
const splited = str.split('/') const r1 = splited[0] const r2 = splited[splited.length - 1]
regex
const splited = str.match(/[^\/]+/g) const r1 = splited[0] const r2 = splited[splited.length - 1]
