No-Fuss Guide To Bug-Free JavaScript Development!

JavaScript is a high-level, dynamic programming language that’s pretty much all around us, and not just on the web – you can find JavaScript in PDF documents, site-specific browsers, as well as desktop widgets. The best part about JavaScript is that it’s a programming language that’s really easy to learn, which makes JavaScript development really appealing to beginners. If you’re just starting to learn JavaScript, or you’re looking to brush up on your JavaScript development skills, we’ve got the right thing for you: we gathered three most important tips every developer should know!

Make Your Code Easy To Understand

Detailed, yet concise and easy to understand comments are the secret of effective code, and should be practiced by every single developer, not just during JavaScript development. Unlike other development niches, single comments in JavaScript development are introduced by // (two forward slashes), and don’t have the closing element. Multi-line comments start with /* and end with */. Whichever style you use, remember that tools for editing the code like minifiers usually remove all the code comments; which can cause you tons of headache down the road.

Check For Errors During Every Step Of JavaScript Development

Keeping track of errors during JavaScript development is as important as writing code comments! Many beginners mistakenly believe that they don’t have to fix an error unless it’s a fatal one that stops the execution, which is the best recipe for a disaster. Our developers usually use the strict mode when programming without a compiler. It’s quite easy to set it up, just add this to the top of your JavaScript files:

'use strict';

Pay Attention To Details

You’d be surprised how many hours beginners spend hunting down an error, only to realize that the they forgot a semicolon or they simply forgot the var tag when declaring a variable! Another common mistake is omitting curly braces after statements like if, else, while and for. Although it is allowed, it can still cause quite a few bugs down the road, so make it a habit to always surround blocks of code with curly braces.

Linting Is Your Friend

Lint checkers can be used to hunt down typos, errors and other little bugs, and the most popular ones are JSHint, JSLint, and Closure Linter, which might not sound like too big of a deal, but once you’re buried under hundreds and thousands of line of code, even a single typo can make your life a living nightmare, which is why these checkers can come in really handy.
