Velocity.js Template Engine

velocityjs is a JavaScript implementation of the Apache Velocity Template Language (VTL), providing a robust solution for server-side and client-side templating. The current stable version is 2.1.5, offering full compatibility with Java Velocity syntax. It distinguishes itself by separating template parsing into an Abstract Syntax Tree (AST) from the rendering phase, allowing for optimized compilation and execution. Key features include high performance, a lightweight footprint, and comprehensive support for VTL directives such as `#set`, `#foreach`, `#if`, and custom `#macro` definitions. While a specific release cadence isn't detailed, the library appears mature and stable, making it a reliable choice for projects needing VTL capabilities in a JavaScript environment.
