 ## freeCodeCamp.org 的开源代码库和课程 [freeCodeCamp.org](https://www.freecodecamp.org) 是一个友好的社区,您可以在这里免费学习编程。它由一家[由捐赠者支持的 501(c)(3) 慈善机构](https://www.freecodecamp.org/donate) 运营,旨在帮助数百万忙碌的成年人转型进入科技行业。我们的社区已经帮助超过 100,000 人获得了他们的第一份开发者工作。 我们的全栈 Web 开发和机器学习课程完全免费且可自主学习。我们提供数千个互动编程挑战,帮助您拓展技能。 ## 目录 - [认证](#certifications) - [学习平台](#the-learning-platform) - [报告错误和问题](#reporting-bugs-and-issues) - [报告安全问题和负责任的披露](#reporting-security-issues-and-responsible-disclosure) - [贡献](#contributing) - [平台、构建和部署状态](#platform-build-and-deployment-status) - [许可证](#license) ### 认证 freeCodeCamp.org 提供多项免费开发者认证。每项认证都要求构建 5 个必需的 Web 应用项目,并包含数百个可选的编程挑战,以帮助您为这些项目做好准备。我们估计,初学者程序员需要大约 300 小时才能获得每项认证。 freeCodeCamp.org 课程中的 50 个项目均包含各自的敏捷用户故事和自动化测试。这些内容可以帮助您逐步构建项目,并确保在提交项目之前已完成所有用户故事。 您可以通过 [freeCodeCamp 的 CDN](https://cdn.freecodecamp.org/testable-projects-fcc/v1/bundle.js) 导入这些测试套件。这意味着您可以在 CodePen 和 Replit 等网站上构建这些项目,甚至可以在您本地计算机的开发环境中构建。 获得认证后,您将永久拥有该认证。您可以随时在 LinkedIn 或简历中链接到该认证。当您的潜在雇主或自由职业客户点击该链接时,他们会看到一份专门为您认证的认证证书。 唯一的例外是,如果我们发现有人违反了我们的[学术诚信政策](https://www.freecodecamp.org/news/academic-honesty-policy/)。如果我们发现有人明显抄袭(未经引用将他人的代码或项目作为自己的作品提交),我们会采取所有严谨的教育机构都应该采取的措施——撤销其认证证书并封禁相关人员。 以下是我们十二项核心认证: #### 1.
