[javascript] How to use forEach in vueJs?

You can use native javascript function

var obj = {a:1,b:2};

Object.keys(obj).forEach(function(key){
    console.log(key, obj[el])
})

or create an object prototype foreach, but it usually causes issues with other frameworks

if (!Object.prototype.forEach) {
  Object.defineProperty(Object.prototype, 'forEach', {
    value: function (callback, thisArg) {
      if (this == null) {
        throw new TypeError('Not an object');
      }
      thisArg = thisArg || window;
      for (var key in this) {
        if (this.hasOwnProperty(key)) {
          callback.call(thisArg, this[key], key, this);
        }
      }
    }
  });
}

var obj = {a:1,b:2};

obj.forEach(function(key, value){
    console.log(key, value)
})
