//已知字符串msg=’get-element-by-id’;,写一个函数将其转化成驼峰表示法：’getElementById’

combo(“get-element-by-id”);

function combo(msg){

var arr=msg.split(“-“);



var i=1;



for(;i<arr.length;i++){




arr[i]=arr[i].charAt(0).toUpperCase() + arr[i].substr(1,arr[i].length);



}



console.log(arr);

//[‘get’,’Element’,’By’,’Id’]




msg=arr.join(“”);



console.log(msg)

//getElementById
