Javascript I Exam Overview

Hello, and welcome to Another Salesforce Blog!  Here I will be posting solutions to problems that I couldn’t find an answer to in hopes of helping those who find themselves stuck when using the Salesforce platform.

This is a long awaited post, as I passed the Javascript Developer I certification in October, and it is now January! What can I say, sometimes life gets in the way.

Much to my surprise and delight, I passed the exam on the first try. Due to COVID restrictions, a lack of testing resources, and a scheduled trip, I took this exam remotely on my laptop, which was a first for me! I had a pleasant overall experience, and will likely take future exams via online proctoring.

Unlike other Salesforce exams, the bulk of the preparation for the Javascript Developer I certification must be done outside of Trailhead. There are a few modules within Trailhead that give basic information, but I found that they were lacking. This is actually great news if you are looking to take the exam to prove your mettle in Javascript, as there is little Salesforce knowledge required to take the exam!

So, how did I review for the Javascript Developer I certification?

Practice, practice, practice.

In addition to completing all of the recommended Trailheads and the Lightning Web Components Superbadge, I took on Lightning Web Components projects at work and I worked my way through the beginning Javascript course on Codecademy as a refresher. If you are new to Javascript, I highly recommend Codecademy (no affiliation!) as it will allow you to build your skills or refresh them by doing.

The bulk of the questions are looking at a block of code and determining the output, so hands on Javascript knowledge is definitely required. This isn’t an exam that can be passed through memorization – you have to have a vague idea of what you’re doing.

In terms of practice tests, there are very good free and paid practice exams on SalesforceCert, and, since I have taken the exam, Focus On Force has updated their offerings to include a paid study guide and set of practice exams.

LinkedIn has a Javascript quiz, which is significantly harder than the questions posed in the Salesforce examination. The downside to this quiz is that you cannot see your answers, just whether or not you scored high enough to earn the badge. The upside is that if you can pass it, you can probably pass the Salesforce exam!

Surprisingly, W3Schools also has a Javascript quiz that has very similar questions to what are on the Salesforce exam. I wouldn’t recommend shelling out for their certification exam, as it would not be worth the paper it was printed on from a career standpoint, but it is an okay free resource.

Thanks for reading, let me know if you have any comments or questions!
