  • 检查字符串结尾 判断一个字符串(str)是否以指定的字符串(target)结尾。

    function confirmEnding(str, target) {
      
      var arr = str.replace(/s+/g, "");
      var bb = arr.substr(arr.length - target.length, arr.length);
      if (bb == target) return true;
      
      return false;
    }
    
    confirmEnding("He has to give me a new name", "n");
