If you wish to follow along with the examples, you should have a React app already set up. The easiest way to do this is with the Create React App tool. To use this, you’ll have Node and npm installed. If you haven’t, head to the Node.js download page and grab the latest ver...
The time() method starts a timer in milliseconds and accepts an argument as the label of a timer. To terminate the timer and retrieve the elapsed (time from the timer's start to its termination) time as the output in the Console, we must supply the same label to the timeEnd() method...
In this post, we covered how to prevent JavaScript timers from stopping when a browser tab is inactive. We looked at why it happens, and how web workers can help. Finally, we saw how to set up HackTimer to fix the issue. If you’d like to get more web development, React and TypeSc...
Building things so they work well in isolation, then piece them together to make the full application makes building applications easier. One thing that really helps with this kind of strategy is to open source your stuff. In this talk, we'll take a look
