js 駝峯命名和下劃線互換

代碼走你

 

// 下劃線轉換駝峯
function toHump(name) {
    return name.replace(/\_(\w)/g, function(all, letter){
        return letter.toUpperCase();
    });
}
// 駝峯轉換下劃線
function toLine(name) {
  return name.replace(/([A-Z])/g,"_$1").toLowerCase();
}


// 測試
let a = 'a_b2_345_c2345';
console.log(toHump(a));

let b = 'aBdaNf';
console.log(toLine(b));
