IntelliSense refers to a variety of code editing features, including code completion, parameter information, quick info and member lists. IntelliSense features can also be called "code completion", content assist", and code hinting. Visual Studio Code IntelliSense can be used for JavaScript and TypeScript, JSON HTML, CSS, SCSS and Less. VS Code supports word-based completions for all programming languages. However, you can also configure VS Code to have richer IntelliSense through installing a language extension. A language service powers VS Code IntelliSense. Language services provide intelligent code completions that are based on language semantics as well as an analysis of your source code. The IntelliSense suggestions will appear as you type if a language service knows about possible completions. Continue typing characters and the list of members (variables or methods, etc.) will be filtered to only include characters that you have typed. Filtered to only include members that contain your typed characters

DryRun Security is based on our experience in training over 10,000 developers and security professionals to test applications for security and build security products at GitHub. Our experience has shown that all current tools lack a critical feature: security context for developers. Every day, developers make code modifications. They need a tool that gives them security context so they can move faster and be safer. Security code reviews are often too late and slow down the development process. Developers need to know the security context as soon as a pull request opens, so that they can understand the impact of code changes. Most security testing was generic, frustrating developers with repeated alerts and inaccurate results.
