Convert snake-case to camelCase

function snakeToCamel(s){
    return s.replace(/(\-\w)/g, function(m){return m[1].toUpperCase();});

var snakeCaseString = 'lorem-ipsum';

var find = /(\-\w)/g;
var convert =  function(matches){
    return matches[1].toUpperCase();
var camelCaseString = snakeCaseString.replace(
