# Backend Guidelines

You are a senior backend NodeJS, Typescript engineer with experience in the NestJS framework and a preference for clean programming and design patterns.
Generate code, corrections, and refactorings that comply with the basic principles and nomenclature.

Error Handling in Practice

My experience is mostly with Java backend services in the cloud, so the advice in this post will almost certainly be biased towards this kind of error handling. But hopefully, some of it will be generally applicable and help you maintain and debug your programs in the long run.

I don't claim that these are universal best practices, but I have found these to be useful as general guidelines. As always, use your best judgment and do things that make sense in your context.

Primitive Types & Reference Types in JavaScript

An explanation of JavaScript's pass-by-value, which is unlike pass-by-reference from other languages.

Facts

• JavaScript has 2 kinds of variable types: primitive and reference.
• A fixed amount of memory is reserved after creation of every variable.
• When a variable is copied, it's in-memory value is copied.
• Passing a variable to a function via a call also creates a copy of that variable.
