Rust for JavaScript/TypeScript Programmers

Class Duration

• 5 days of comprehensive training
• Tailored for JavaScript/TypeScript developers

Target Audience

• Proficiency in JavaScript/TypeScript programming
• Basic understanding of programming concepts such as variables, expressions, functions, and control flow

Training Materials

All students receive comprehensive courseware covering all topics in the course. Courseware is distributed via GitHub in the form of documentation and extensive code samples. Students practice the topics covered through challenging hands-on lab exercises.

Software Requirements

Students will need a free, personal GitHub account to access the courseware. Students will need permission to install Rust and Visual Studio Code on their computers. Also, students will need permission to install Rust Crates and Visual Studio Extensions. Students will need a local instance of Postgresql or SQL Server installed on their computer (using Docker is acceptable). Finally, students will need CURL and/or Postman installed on their computer. If students are unable to configure a local development environment, a cloud-based environment can be provided.
