Answer 1

function trans (str) {

    let r = str.split('_')

    return [r[0], r.slice(1).join('_')]

}

trans('aa_bb_cc')

Answer 2

var s = 'aa_bb_cc';

var index = s.indexOf('_');

var rs = [s.slice(0, index), s.slice(index+1)];

console.log(rs);

let str = 'aa_bb_cc';

let arr = str.split('_',1);

str = str.slice(str.indexOf('_')+1);

arr.push(str);
