Luckily, Node.js ships with the NPM CLI, a command-line interface that allows software developers to share libraries and manage dependencies easily. Having package management experience is an essential skill for every Node.js developer, as you would be working with them all the time. ES6 introduced the let and const keywords, which are blocked scoped declarations that are not prone to the errors common to the var keyword. ES6 also provides a better asynchronous operation, in the form of async & await, and promises to handle the results of requests and possible errors.<\/p>\n<\/p>\n

Explore top monitoring tools and techniques specifically designed for Node.js applications running in Docker. Explore the key differences between Node.js and Java, guiding senior developers through performance, scalability, and use cases to make informed decisions. Learning about async programming and callbacks in Node.js is super important. Make sure you understand how to handle asynchronous operations using Promises and async\/await. It can be a bit tricky at first, but once you get the hang of it, your code will be much more efficient and easier to maintain.<\/p>\n<\/p>\n
