Mozilla actually shows you how to handle objects with push by chaining push to the call method: "push is intentionally generic, and we can use that to our advantage. Array.prototype.push can work on an object just fine, as this example shows. Note that we don't create an array to store a collection of objects.

1: Push a certain amount of the same function (with a different parameter in each) into an array. function func(num){ alert(num); } var k = []; k.push({f:func, params:[1]}); k.push({f:func, params:[2]}); k.push({f:func, params:[3]}); 2: Then run each function one by one (for this example just an alert of the parameter/number)

Dec 9, 2008 · The result of .push in the scenario will be = [ar1, [ar2]]. .concat solves that problem, but with sacrifice of speed and a new array created. To use .push properly in array appends, loop out the contained element first and push each. ar2.forEach(each => { ar1.push(each); }); –

Aug 20, 2013 · I am trying to do something similar to what Google Analytics is doing. I want to push a function name along with parameters into an array and then execute the function name along with the parameter. For example: var _test = _test || []; _test.push(['setName', 'Todd']); And execute setName in here:

Jan 8, 2023 · Webflow.push(function() {}) JavaScript is a very flexible language where you can find functions in many different situations: functions which call themselves, functions associated with keys in object literals, functions inside other functions, and of course, functions in arrays...

Nov 5, 2015 · push also accepts multiple arguments and increments length (since it's a generic method and works on non–array objects too). It also checks that the lengthened array will have a length < 2^53-1, so it's possible to get a lot closer than that.

May 1, 2020 · Once you pass a function like you did in the second case, it executes itself immediately, and array.push doesn't really mean something. A callback function should be executed later on in the outer function. Unlike the second example, in the first one you don't execute the function immediately, but only when you call it inside the outer function.

Dec 9, 2014 · That's why the push and pop methods will happily use an object instead of an array as long as it has a length property. – Guffa Commented Dec 9, 2014 at 19:14

The below solution is more straight-forward. All you have to do is define one simple function that can "CREATE" the object from the two given items. Then simply apply this function to TWO arrays having elements for which you want to create object and save in resultArray.

I don't understand what the function reduce is doing, but the problem is that Array.prototype.push returns the length of the array. var array = [1,2,'b']; var val = array.push('foo'); // val === 4; Therefore, instead of re-setting current every iteration of your loop, just simply call the function since .push() modifies the array in place.
