The Salesforce JavaScript Developer Certification

Every JavaScript developer can easily build on Salesforce with Lightning Web Components. Developers can use the existing portfolio of developer services in the Lightning Platform and the modern JavaScript language to build and deploy blazing fast apps on Salesforce.

The certification consists of two parts: the JavaScript Developer proctored multiple-choice exam and the Lightning Web Components Specialist superbadge. These two certifications can be earned in any sequence. The combination of both of these certifications automatically earns the Salesforce Certified JavaScript Developer certification.

Using this two-part approach, this certification validates both the core JavaScript skills and hands-on development skills of Trailblazers who need to work with JavaScript related technologies like the Lightning Component Framework, and specifically Lightning Web Components. Lightning Web Components are custom HTML elements built using standard HTML and modern JavaScript.

These are the typical job roles that align to the Salesforce Certified JavaScript Developer.

The Salesforce JavaScript Developer multiple-choice exam is designed for individuals who have knowledge, skills, and experience developing front-end or back-end JavaScript applications for the web stack.

The Salesforce JavaScript Developer minimally qualified candidate can use the JavaScript language in one or more frameworks to develop front-end and/or back-end applications. The candidate can design, develop, and test solutions that are performant, maintainable, and reusable.

The candidate can use JavaScript-specific design patterns for programming, and can combine JavaScript with CSS, HTML, and other markup languages.

This exam covers these key topics, each making up a certain percentage of the exam.

Variables, types, and collections: 23%
Objects, functions, and classes: 25%
Browsers and events: 17%
Debugging and error handling: 7%
Asynchronous programming: 13%
Server-side JavaScript: 8%
Testing: 7%

By successfully passing the Salesforce JavaScript Developer multiple-choice exam, you demonstrate a thorough knowledge and understanding of JavaScript and the fundamental skills needed to develop Lightning web components.
