Javascript tips

Type mdn.io/[your query here] to go straight to the mdn page for it.

For example:mdn.io/canvasmdn.io/localstoragemdn.io/webrtcIn most cases it'll get you to where you want to go, rather than googling "mdn canvas" or similar.

You can declare a default value when destructuring.

Example: const { id = 7 } = {} console.log(id) // 7 This protects from setting "id" above to undefined. And you don’t have to declare a separate null check. ​Origin : Cory House

Make Sure That You Take Plenty Of Notes

Note-taking is an essential part of learning JavaScript. Even though I have an in-depth knowledge of a range of different programming languages, I still take notes every time I sit down to learn new coding skills. Taking notes allows you to put difficult concepts and ideas into words that you understand. This lets you return to your notes at a later date and can help you understand things that you are having trouble with. Having notes to return to can also help you study and can reinforce your knowledge. The simple act of writing things down can help you remember them. If you want to learn JavaScript, then the first thing you need to do - before you even enroll in a course or start watching 'how to code' videos - is to head down to your local stationery store and buy a notebook. Grab a few different colored pens, a couple of highlighters, and set yourself up for some serious note-taking.

Connect With A Mentor

Now, as any beginner programmer will know, learning to code can be boring, tedious, and downright frustrating at times. It can be hard to stay motivated to learn JavaScript or any other language, and sometimes you will be tempted to just give up. If you feel like this, then it could be time for you to connect with a coding mentor. A mentor is someone willing to help you improve your coding skills, write great programs, and eventually, become a career programmer. If you're lucky, you will be able to find a mentor who is willing to help you for free, but it is equally likely that you will have to pay someone - after all, who wants to work for free? If you are looking for a free mentor, then start getting active on coding forums and chat rooms online. Attend local meetup groups or organized events, and connect with people in the industry - you never know, you might just get lucky! However, if you can't find a free mentor, you will need to pay someone to help you. While this may be out of reach of some people in a financial sense, even an hour or two of mentoring per week can help you come to a better understanding of difficult topics. If you are looking for a coding mentor to learn JavaScript and who you can connect with regularly, head over to Rookie Up and start connecting with potential mentors.

Don't Be Afraid To Practice

If you want to become a fluent programmer or web developer, then you need to commit yourself. One of the most important parts of the learning process is practice. If you don't practice writing code, then you will never improve. It could be argued that you are wasting your time working through an online course if you aren't willing to put time into practicing your code outside of your course. As noted above, to be able to improve and learn JavaScript, you need to download your code editor. Once you have a code editor, it is very easy to practice writing and editing code. Head over to GitHub and having a look at some of the open-source code available there. Find a piece of code that looks interesting, download it and open it in your code editor, and work through it until you understand what every line of the code does. Another great way to practice writing JavaScript code is by completing 'coding challenges'. A simple Google search will reveal hundreds of such challenges, which are designed for and aimed at people who are learning and who want JavaScript examples that they can work through. Choose something that is aimed at your skill level, practice, and don't be afraid to ask for help if you need it - but more on that in a moment. Above all, make sure that you remember: "Perfect practice makes perfect" No, practice doesn't make perfect - perfect practice does. Make sure that you are following best practices and not getting lazy when you practice writing JavaScript code, otherwise, you will start picking up bad habits.

Use A Good Online Course

There are many methods you could choose if you are trying to learn JavaScript. If you are an experienced programmer who already has an in-depth knowledge of coding basics, learning JavaScript - or any other language - should be a relatively easy process. Simply by watching videos, reading tutorials, and practicing writing increasingly complex programs in your code editor. However, it can be a lot more difficult as a beginner with no coding experience. You could attend a coding boot-camp, but this will cost you a lot of money and involves a full-time commitment for at least 3 months (in most cases). Alternatively, you could enroll in a university computer science course. However, this requires an even greater time commitment, and you won't be able to start working as a programmer for at least 3 years if you take this path. Last, but not least, you could use a high-quality online course to guide you. Using an online course has a wide range of benefits over things like boot-camps and university courses. These include things like:

  • Many online courses give you the chance to learn JavaScript free - something you could never go through university or intensive courses. You can also apply for scholarships which can help you pay for the fees of JavaScript courses.
  • Online courses let you work at your own pace. This is great for people who work during the day and want to spend a few hours a week learning JavaScript. I have developed most of my coding knowledge by spending an hour or two every night working through various online courses.
  • In general, online courses are structured to give you the optimal learning experience. If you use them alongside things like reference guides and coding forums, you should be able to learn your chosen languages quickly and efficiently. If you are looking for an online course to help you learn JavaScript, then you need to have a look at the wide range of courses on the BitDegree platform. Here you will find many great JavaScript courses, including the Interactive JavaScript tutorial, which introduces JavaScript basics in a simple, straightforward manner. Alternatively, get started with the Video JavaScript Tutorial, which looks at simple syntax and some of the things you can do with JavaScript.

Download A Code Editor Or Use One Online

Although your course may not require you to use a desktop code editor, it's a very good idea to get used to using one as you learn. Although you can learn JavaScript - and most other programming languages - through online courses that allow you to write code directly in your internet browser window, you will need to be able to use a desktop code editor if you ever want to land a job as a developer. The Atom code editor is one of the best when it comes to writing high-quality JavaScript code. It is relatively easy to use, it is free, and it offers a range of useful features, including:

  • A built-in IDE.
  • Compatibility with a range of languages, allowing you to work on many different programs through the same Atom interface.
  • Simple Git and GitHub integration. Downloading the Atom code editor is relatively simple. To begin with, you need to head to the Atom website. Click on the 'download' button near the top of the homepage, and follow your computer's prompts. Although it is relatively straightforward to use, you might benefit from reading the Atom Flight Manual. This document covers everything you need to know about using Atom to write, edit, and organize code. If you don't want to download anything, BitDegree provides a free online code editor where you can try out various examples of JavaScript and code your own. and every single line of code that you write, what it does, and how it impacts the rest of your program. The difference between the words "to master" and "to learn JavaScript" is gigantic. Every time you write a program, you need to sit down for a few minutes and make sure that you know what every little bit of code does. If you are unsure about something or don't understand it, go back over your notes, have a look in a language reference guide (more on this in a minute), or ask someone for help.
