I want to wrap all Array functions in array object, but in console
>>> Array.prototype
[]
>>> [].prototype
undefined
but when I type Array.prototype in console it show all functions in autocomple, how can I get those functions? Where are they hidden?
do you mean:
var arrObj = Object.getOwnPropertyNames(Array.prototype);
for( var funcKey in arrObj ) {
console.log(arrObj[funcKey]);
}
arrObj is actually an array and looping an array with for..in has it's drawbacks.
Object.getOwnPropertyNames(myArr); is this possible?Object.getOwnPropertyNames(myArr.__proto__). I know this is an old question but someone just upvoted my question and I've checked the answers.Using ECMAScript 6 (ECMAScript 2015), you can simplify a bit:
for (let propName of Object.getOwnPropertyNames(Array.prototype)) {
console.log(Array.prototype[propName]);
}
var proto = Array.prototype;
for (var key in proto) {
if (proto.hasOwnProperty(key)) {
console.log(key + ' : ' + proto[key]);
}
}
And if you want to check its property in console.
Use: console.dir(Array.prototype);
console.dir(Array.prototype); return array[0] with those functions, but iterating over Array.prototype don't work.
Array.prototype.pop. Aditionaly [].prototype is undefined to get prototype of Array object I need to use [].constructor.prototype
getRandom is listed, but map isn't.)
