Destructuring and Function Arguments

  • The JavaScript language has benefitted from some really awesome new features over the past few years, including arrow functions, the spread operator, and default function argument values.
  • One of my favorite new(ish) JavaScript features is object destructuring.
  • If you aren’t familiar with JavaScript destructuring, it basically provides a shorter syntax for extracting an object key’s value without the dot notation mess: – – The basic syntax for destructuring is fairly simple but using destructuring with function arguments can be a bit more difficult when those argument values…
  • The following is a function with arguments having default values: – – Regardless of language, if a function takes more than ~3 parameters, it’s probably best to pass in an object name  or  that contains possible key/values; the equivalent would look like: – – What if you want to use…
  • The following function signature would become: – – If you want to define defaults in the function configuration, you’d use the following: – – Setting a default with is important; with no default the following example would error: – – Destructuring is an awesome language feature but can lead to…

Debounce Your React and Redux Code to Improve Performance

Debounce Your #ReactJS and Redux #Code to Improve Performance:  by @TreyHuffine #JavaScript

  • Debounce Your React and Redux Code to Improve PerformanceA debounce is a tool that every web developer should have in their kit.
  • Let’s take a look at the individual steps to understand how much we actually saved.After the debounce time expires after the final key press, the first step is to make our API call.
  • Since we have debounced the function that fetches from our API, we only make the request once at the end of typing into the input.There are two things happening here — retrieving projects from the database and then performing heavy calculations to filter and sort the data.
  • By debouncing, we prevent the setState() which serves to significantly reduce the number of times we force React to reconcile and append the list to the DOM.Without a debounce, this component would be almost unusable with such a large amount of data.
  • In addition, you should consider wrapping any interaction that triggers excessive calculations or API calls with a debounce.

A debounce is a tool that every web developer should have in their kit. It improves performance by limiting the number of expensive calculations, API calls, and DOM updates. Although the debounce…

An open source library for using D3 in React — WDstack — Medium

react-d3-library - #reactjs friendly bindings for the D3 visualization library

  • It first creates a virtual DOM and then uses a diffing algorithm to determine if the DOM needs to update.
  • Then the element is passed to the library’s custom React Component as state.
  • The way elements are first mounted to the DOM through React, and can then benefit from React’s Lifecycle methods like componentWillUnmount.
  • The way the React D3 Library works is the user first gives D3 a generic DOM element to work with rather than an element on the actual DOM.
  • But D3 will temporary be given access to the DOM after they have mounted, to directly apply the complex transitions, animations, etc.
