The JS-Dev-101 exam is the official Salesforce exam behind Salesforce Certified JavaScript Developer - Multiple Choice — passing it earns you the Salesforce Developers certification, a credential positioned at the Elementary level. It is built for candidates who want to validate the skills measured by Salesforce Certified JavaScript Developer - Multiple Choice. Depending on your track, the exam is also linked to the Salesforce Certified JavaScript Developer I and Lightning Web Components Specialist Superbadge certifications, so one pass can move you toward more than one Salesforce credential.

The JS-Dev-101 exam presents 60 (plus up to 5 unscored pilot questions) questions to be completed within 105 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.

To pass the JS-Dev-101 exam you need 65%, and the official registration fee is $200 USD. Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.

Completion of the Lightning Web Components Specialist Superbadge is required to earn the full credential, though it can be completed before or after the exam. Because Salesforce revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official Salesforce exam page before you register.
