Salesforce JavaScript Developer I

Those with knowledge, expertise, and experience creating front-end and/or back-end JavaScript applications for the web stack should pursue the Salesforce Certified JavaScript Developer I certification. These abilities are neither mobile or device-specific and can be used with any framework.

This certification verifies applicants’ proficiency with both the fundamentals of JavaScript and practical development abilities necessary to work with JavaScript-related tools like the Lightning Component Framework and, more specifically, Lightning Web Components. Lightning web components are unique HTML elements created with current JavaScript and conventional HTML.

The proctored multiple-choice exam for JavaScript Developer I and the superbadge for Lightning Web Components Specialist make up the certification. These two certifications can be obtained in any order. Only JavaScript is covered in the multiple-choice exam, but Lightning Web Component development skills are covered in the superbadge.

Target Audience

The Salesforce Certified JavaScript Developer I certification candidate creates front-end and/or back-end applications using the JavaScript language in one or more frameworks. The applicant is capable of designing, creating, and testing effective, maintainable, and reusable solutions.

The applicant is proficient in programming using JavaScript-specific design patterns and fusing JavaScript with HTML, CSS, and other markup languages.

With Lightning Web Components, any JavaScript developer can simply build on Salesforce. This means that the many JavaScript programmers who work on Salesforce won’t need to learn any new skills. To create and deploy lightning-fast apps on Salesforce, developers can make use of the portfolio of developer services already available in the Lightning Platform and the current JavaScript programming language.

The Salesforce Certified JavaScript Developer I certification is aimed for Salesforce partners, customers, and staff who utilise JavaScript and have knowledge, expertise, and experience creating Lightning Web components (LWCs).

The following are typical job roles that fit the Salesforce Certified JavaScript Developer I:
