This article will explain what asynchronous code is, some of the difficulties of using asynchronous code, and ways of handling these difficulties. What is the difference between synchronous and asynchronous code? Synchronous code In synchronous programs, if you have two lines of code (L1 followed by L2), then L2 cannot begin running until L1 has finished executing. You can imagine this as if you are in a line of people waiting to buy train tickets.
Automated tests enhance software stability by catching more errors before software reaches the end user. They provide a safety net that allows developers to make changes without fear that they will unknowingly break something in the process. The Cost of Neglecting Tests Contrary to popular intuition, maintaining a quality test suite can dramatically enhance developer productivity by catching errors immediately.
Three of the most popular solutions are Grunt, Gulp and Webpack. Each of these tools are built on different philosophies, but they share the same common goal: to streamline the front-end build process. For example, Grunt is configuration-driven while Gulp enforces almost nothing. In fact, Gulp relies on the developer writing code to implement the flow of the build processes - the various build tasks. When it comes to choosing one of these tools, my personal favorite is Gulp.
…or how solving code puzzles can be your path to enlightenment. Whenever I’m asked how a developer can learn more about a particular language, I stress that it’s crucial to find the technique that works best for you. Most folks can think of a few immediate ways to pick up a new language: BooksConferencesClassroom study While these work, they’ve always had a few drawbacks for me. When it comes to books, I find that they are only effective if I read them while I’m sitting by my computer. Because I love reading so much, I actively try not to read by my computer.
Conferences are great, but typically they give you a 60 minute intro to a language or topic, and at best inspire you to work on it more on your own time. And of course – actually spending time in a classroom can be incredibly productive. One thing you may notice about the suggestions above is that in each case, I talk about “playing” or working on code while I’m learning.
