课程名称：Salesforce认证JavaScript开发者I考试准备 课程概述： Salesforce认证JavaScript开发者I证书面向具有开发JavaScript网页应用经验的个人，无论是在前端、后端或两者之间。该证书验证核心JavaScript技能以及在Salesforce中使用JavaScript的实践经验，特别是通过Lightning Web Components（LWC）框架。LWC允许开发人员使用标准HTML和现代JavaScript创建快速、可重用的组件。由于LWC基于通用网页标准，JavaScript开发人员可以利用现有技能在Salesforce平台上构建应用程序，同时减少学习时间。 证书内容： 该认证由两部分组成： 1. JavaScript开发者I考试 - 一项针对核心JavaScript概念的多项选择考试 2. Lightning Web Components专家超级徽章 - 一项实践评估，验证使用LWC构建应用程序的能力 这两部分可以按任意顺序完成，获得两者即可自动授予Salesforce JavaScript开发者I证书。 适合人群： 此认证旨在面向希望将JavaScript技能应用于Salesforce生态系统的个人。典型角色包括： - JavaScript开发者 - Salesforce开发者 - 全栈开发者 - 前端或后端网页开发者 - UI/UX工程师 - 技术项目或产品经理 - 支持工程师 考生应能够： - 使用JavaScript构建和测试高效、可重用的组件 - 运用标准JavaScript编程模式，与HTML、CSS和网页API协作 - 在Lightning Web Components和Salesforce平台的背景下应用JavaScript基础知识 考试信息： Salesforce JavaScript开发者I考试是现代JavaScript开发者的标准认证。考试内容包括60道多项选择/多选题，最多包含5道不计分题，考试时间为105分钟，及格分数为65%。考试费用为200美元（加上适用税费），重考费用为100美元（加上适用税费），可在线或现场监考进行。 考试大纲： 考试评估考生在以下各部分所需的知识和技能： - 变量、类型和集合：23% - 对象、函数和类：25% - 浏览器和事件：17% - 调试和错误处理：7% - 异步编程：13% - 服务器端JavaScript：8% - 测试：7% 此课程对Salesforce员工、合作伙伴和客户均有重要意义，特别是那些希望使用JavaScript和LWC开发自定义Salesforce应用程序的人。
About the Salesforce JavaScript Developer I CredentialThe Salesforce Certified JavaScript Developer I credential is for individuals with experience developing JavaScript applications on the web, whether working on the front end, back end, or both. This certification confirms core JavaScript skills as well as hands-on experience using JavaScript within Salesforce, particularly through the Lightning Web Components (LWC) framework.LWC allows developers to create fast, reusable components using standard HTML and modern JavaScript. Because LWC is based on common web standards, JavaScript developers can use their existing skills to build applications on the Salesforce Platform with minimal ramp-up time.What the Credential CoversThe certification consists of two parts:JavaScript Developer I Exam - A multiple-choice exam focused on core JavaScript conceptsLightning Web Components Specialist Superbadge - A hands-on assessment that validates the ability to build applications using LWCThese can be completed in any order. Earning both automatically grants the Salesforce JavaScript Developer I credential.Who This Is ForThis certification is intended for individuals who use JavaScript to build web applications and want to apply those skills within the Salesforce ecosystem. Typical roles include:JavaScript DeveloperSalesforce DeveloperFull Stack DeveloperFront-End or Back-End Web DeveloperUI/UX EngineerTechnical Project or Product ManagerSupport EngineerCandidates should be able to:Build and test performant, reusable components using JavaScriptUse standard JavaScript programming patterns and work with HTML, CSS, and web APIsApply JavaScript fundamentals in the context of Lightning Web Components and the Salesforce PlatformThis credential is relevant for Salesforce employees, partners, and customers who work with or plan to develop custom Salesforce apps using JavaScript and LWC.About the ExamThe Salesforce JavaScript Developer I Exam is a standard credential for developers working with modern JavaScript.Content: 60 multiple-choice/multiple-select questions, with up to 5 unscored itemsTime allotted: 105 minutesPassing score: 65%Version: Based on Summer '22 releaseRegistration fee: $200 USD (plus applicable taxes)Retake fee: $100 USD (plus applicable taxes)Delivery: Online or in-person proctored examReferences: No materials permitted during the examPrerequisite: NoneCandidates may also provide comments or 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.
