CommonJs Vs EcmaScript Modules | Sigma Web Development Course - Tutorial #86

Summary

This video script discusses two methods of creating modules in Node.js: using a single script with the t6 module and using common JS modules. It guides viewers through setting up a project with npm and demonstrates installing multiple modules, as well as the use of 'require' and ES6 'import' syntax for module management. The script also covers using 'nodemon' for development to automatically restart the server on file changes, and it touches on the importance of understanding module syntax for expert-level JavaScript development.
