The Salesforce Certified JavaScript Developer I is intended for individuals who have knowledge, skills, and experience developing front-end and/or back-end JavaScript applications for the web stack. These skills can be applied to any framework and are not mobile or device specific.
The certification consists of two parts: the JavaScript Developer I proctored multiple-choice exam and the Lightning Web Components Superbadge. These two credentials can be earned in any sequence. The combination of both of these credentials automatically earns the Salesforce Certified JavaScript Developer I certification.
