Measuring code execution performance in JavaScript by Gav Learn about Parsing and Writing YAML files using Symfony's YAML component. In this tutorial we will look at using YAML in PHP. Reading/Parsing and Writing YAML files, PHP Symfony by Gav Use Implements to implement interfaces and types, and extends to inherit from classes. Learn the difference between implements and extends in TypeScript. Implements and Extends, Object Oriented TypeScript by Gav

At this point we could also push the elements to an array const boxes = document.getElementsB圜lassName('box') From here we could loop our array-like object ‘as-is’ or push each iteration to a new array (in this case ‘boxArray’) for a future use. Last, but not least, you could solve this problem the good old fashioned way with a simple iterator loop. slice.call(document.getElementsB圜lassName('box')) Convert to array using an iterator loop var boxes = (document.getElementsB圜lassName('box')) Basically we are using the array method ‘ slice‘ (which returns a copy of an array) on an array-like object with a ‘call’ method, and then saving the copy into a new array object. slice.call for short) methods for converting.

More widely supported, we can use the () (or. You should note that this method isn’t actually supported by Internet Explorer, but who cares about Internet Explorer now anyway… const boxes = om(document.getElementsB圜lassName('box')) Convert to array using () This is my preferred method of converting to array because it is semantically very easy to read at a glance. The code looks something like this: const boxArray = Convert to array using om()Īom does what it sounds like it converts array-like objects to actual arrays. This works because the HTMLCollection is iterable.

Convert to array using a spread operatorĪ spread operator will allow us to expand the values of our array-like object and push them into a new array. Here are 4 ways to convert the returned HTMLCollection to an array. Ĭonst boxes = document.getElementsB圜lassName('box') Each div has the same class and we query for a HTMLCollection using ‘ getElementsB圜lassName‘. Let’s start with a simple scenario where we have 5 divs. Today I’m going to show you how to make these objects a little bit more useful, by converting them into JavaScript arrays. They include objects with a length property, such as HTMLCollection, NodeList, argument list and even strings. Facebook Share Twitter Share LinkedIn ShareĮver had an array-like object that you want to iterate over? These annoying collections, which look like arrays, don’t have access to useful array methods like the ‘ forEach‘ loop.

For each javascript object
