课程名称：Salesforce认证JavaScript开发者I题目 *新* 概述： Salesforce认证JavaScript开发者I凭证针对那些具有经验，能够为Web平台创建前端和后端JavaScript应用程序的专业人士。评估的技能适用于各种框架，并不局限于移动设备或特定设备。该凭证测量基础JavaScript理解以及使用Lightning组件框架的实际技能，重点关注Lightning Web Components（LWC）。LWC是使用标准HTML和现代JavaScript技术创建的自定义HTML元素。 该认证包括两个部分：一个有监考的多项选择考试和一个Lightning Web Components专项超级徽章，二者可以任意顺序进行。考试考核JavaScript基础知识，而超级徽章则审查开发Lightning Web Components的实际技能。完成这两个部分后将获得Salesforce认证JavaScript开发者I凭证。 适合对象： 此认证适合那些在一个或多个框架中使用JavaScript来开发基于Web的前端和后端应用程序的个人。候选人需要设计、构建和测试高效、可维护且可重用的解决方案。期望的证书持有者应了解JavaScript编程模式，能够将JavaScript与CSS、HTML及其他标记语言结合使用，并利用Lightning平台创建和部署应用程序。 该凭证对Salesforce的合作伙伴、客户和员工尤为有益，尤其是那些熟悉JavaScript和Lightning组件框架的人。与此认证相关的常见职位包括JavaScript程序员、Salesforce开发者、全栈开发者、Web应用程序开发者、前端开发者、软件/后端开发者、支持工程师、技术产品/项目经理以及UI/UX工程师。 考试信息： JavaScript开发者I考试是JavaScript社区内备受尊重的凭证，适合那些拥有1-2年Web JavaScript应用程序开发经验的人员。该考试验证了开发各种JavaScript技术所需的基本JavaScript开发技能。Lightning Web Components模型的一个显著特点是其依赖于标准JavaScript，使其对已经掌握该语言的开发者非常友好。通过此考试显示出候选人具备扎实的JavaScript基础，并能够创建Lightning Web Components。 考试关键细节： - 格式：60道多项选择/多选题，外加最多5道不计分问题 - 考试时长：105分钟 - 通过分数：65% - 注册费：$200（加上适用的税费） - 重考费：$100（加上适用的税费） - 考试方式：在测试中心或在线进行的监考考试 - 参考资料：考试期间不允许携带任何材料（纸质或在线） - 先决条件：无 - 考生在考试期间可对个别题目提供反馈 考试大纲： Salesforce JavaScript开发者I考试测量候选人在以下各部分及目标方面的知识和技能： 1. 变量、类型和集合：23% 2. 对象、函数和类：25% 3. 浏览器和事件：17% 4. 调试和错误处理：7% 5. 异步编程：13% 6. 服务器端JavaScript：8% 7. 测试：7% 通过学习本课程，学员将提高对JavaScript及其在Salesforce开发中的应用能力，为实现高效的Web开发打下坚实基础。
About the Salesforce JavaScript Developer I CredentialThe Salesforce Certified JavaScript Developer I Credential targets professionals experienced in creating both front-end and back-end JavaScript applications for web platforms. The skills evaluated are adaptable across various frameworks and are not tied to mobile or specific devices.This credential measures foundational JavaScript understanding alongside hands-on abilities with technologies such as the Lightning Component framework, focusing on Lightning Web Components (LWC). LWCs are custom HTML elements created using standard HTML and modern JavaScript techniques.The certification is composed of two parts: a proctored multiple-choice exam and the Lightning Web Components Specialist Superbadge. These can be taken in any order. The exam tests JavaScript fundamentals, while the superbadge reviews practical skills in developing Lightning Web Components. Completing both parts grants the Salesforce Certified JavaScript Developer I credential.Who Should Pursue This Credential?This certification suits individuals who use JavaScript across one or more frameworks to develop web-based front-end and back-end applications. Candidates design, build, and test solutions that are efficient, maintainable, and reusable.Prospective certificate holders are knowledgeable in JavaScript programming patterns and can combine JavaScript with CSS, HTML, and other markup languages. They can use the Lightning Platform to create and deploy applications leveraging modern JavaScript and Lightning Web Components.The credential is beneficial for Salesforce partners, clients, and employees familiar with JavaScript and the Lightning Component framework, including those who build LWCs.Common job roles that align with this certification include:JavaScript ProgrammerSalesforce DeveloperFull Stack DeveloperWeb Application DeveloperFront-End DeveloperSoftware/Back-End DeveloperSupport EngineerTechnical Product/Project ManagerUI/UX EngineerAbout the ExamThe JavaScript Developer I exam is a respected credential within the JavaScript community. It is intended for those with 1-2 years of experience developing JavaScript applications for the web. The exam validates essential JavaScript development skills necessary for various JavaScript technologies.A notable aspect of the Lightning Web Components model is its reliance on standard JavaScript, making it accessible to developers already skilled in the language. Passing this exam shows that candidates possess solid JavaScript fundamentals and can create Lightning Web Components.Key Details about the Exam:Format: 60 multiple-choice/multiple-select questions, plus up to 5 non-scored questionsDuration: 105 minutesPassing Score: 65%Registration Fee: $200 (plus applicable taxes)Retake Fee: $100 (plus applicable taxes)Delivery: Proctored exam available at testing centers or onlineReferences: No materials (hard-copy or online) permitted during the examPrerequisites: NoneCandidates have the chance to provide feedback on individual questions during the exam.Exam OutlineThe Salesforce JavaScript Developer I Exam measures a candidate's knowledge and skills related to the following sections and objectives.Variables, Types, and Collections: 23%Given a scenario, write code to create variables and initialize them correctly.Given a business requirement, utilize strings, numbers, and dates effectively.Given a scenario or example, demonstrate awareness of type coercion and its effects.Given a specific scenario, distinguish truthy or falsey evaluations.Given a list of data, demonstrate data manipulation with arrays.Given a JSON response, demonstrate how to operate the JSON object.Objects, Functions, and Classes: 25%Given a business requirement, locate the best function implementation.Given a business requirement, apply fundamentals of object implementation to solve the business requirement.Given a business requirement, apply fundamentals of class implementation to solve the business requirement.Given a JavaScript module, give examples of how to use the module.Given a JavaScript decorator, give examples of how to use the decorator.Given a block of code, analyze the variable scope and the execution flow.Browser and Events: 17%Given a business requirement, utilize Events, event handlers, and propagation.Given a business requirement, evaluate and manipulate the DOM.Given a scenario, utilize the Browser Dev Tools to investigate code behavior.Given a scenario and requirements, utilize browser specific APIs.Debugging and Error Handling: 7%Given a scenario, handle errors properly.Given code to be debugged, use the console and breakpoints.Asynchronous Programming: 13%Given a scenario, apply asynchronous programming concepts.Given a scenario, use event loop and event monitor or determine loop outcomes.Server Side JavaScript: 8%Given a scenario and requirements, infer which Node.js implementation is a good solution.Given a scenario and requirements, infer which Node.js CLI command is a good solution.Know the core Node.js modules and given requirements, infer which Node.js library/framework is a good solution.Given a scenario and requirements, distinguish which Node.Js Package Management solution is the most fitting.Testing: 7%With a block of code and the associated Unit Test, determine where the test is ineffective and modify it to make it more effective.
