Salesforce Javascript Developer 1 Certification is a proctored exam from The exam is proctored by Kryterion and can be taken either onsite or online. The certification exam is made up of 60 multiple choice Questions with 105 Minutes to complete it. Passing score is 65%. Registration fees for the exam are 200$ and retake is 100$.

In the very first week of 2021 I was lucky to pass the Javascript Developer 1 certification. To get this certification you must complete the LWC Specialist Superbadge and the multiple choice exam (in any order). This article focuses on resources to learn javascript from scratch and ace your Multiple Choice Exam. As a Salesforce developer, learning javascript from scratch was easy for me, so if you’re a salesforce developer it’ll probably be easy for you as well.

Lightning Web Components Specialist Superbadge

I preferred going for the superbadge first and my knowledge with LWC helped me pass it in a short span of time, If you’re just starting with LWC I suggest you read my article on Learning LWC from Scratch. The amount of stuff you’ll learn throughout this superbadge is massive. If you’re stuck with a challenge in the superbadge you can seek help on the Trailblazer Community.

Multiple Choice Exam

This exam is new of it’s kind as there is no past knowledge of the Salesforce platform required to take it. This exam is testing your knowledge and experience with modern JavaScript development using the latest concepts and design patterns that were introduced since ECMAScript 6. I went through the following steps to learn javascript:

1- Salesforce JavaScript Developer 1 Certification Series

Nikhil Karkra did a great job going through each topic included in the exam and explaining it with examples. This playlist consists of 8 videos each one represents a topic on the exam and one video containing practice questions on javascript. Watch it, take notes and apply the scenarios yourself.

2- Trailhead

The Official Trialmix for this certification will give you additional hands on practice, so make sure you complete it.

3- Focus On Force Study Guide

Focus On Force recently released the Javascript Study Guide and practice tests. I got them both and I can tell you that they covered a lot of the ideas I saw on the exam and this is mainly what made me pass this certification. My advice here is to practice everything you learn on the study guide, not just read it because this will help you remember it on the exam.

4- Practice Tests

In addition to the two practice tests on FocusOnForce, and the 25 questions on Salesforce Troop, complete the practice questions on this Trailmix and you’re good to go!
