Closure Compiler
The Closure Compiler is a tool for making JavaScript download and run faster. Instead of compiling from a source language to machine code, it compiles from JavaScript to better JavaScript.
Klocwork
Perforce Klocwork is an enterprise grade SAST solution for C, C++, C#, Rust, Java, JavaScript, Python, and Kotlin. It helps development teams detect security vulnerabilities, quality issues, and reliability defects early, while supporting compliance with industry and regulatory standards. Klocwork is purpose built to analyze very large, complex codebases and scales to hundreds of millions of lines of code, well beyond the practical limits of many traditional SAST tools. This makes it especially suited for organizations developing long lived, safety critical, or security critical systems.
