AppSignal·4yPatterns and Anti-patterns in Node.js
There are two ways to declare variables in JavaScript: var and let. var declares a function-scoped variable (when declared within a function) Let and const declare block- scoped variables. With let and const, you won't be able to use a variable that has not been declared.
gitconnected·4yProduction code: Top 5 Best practices
Make your objects immutable. Enums for well-defined values should be used. Choose the correct logging level. Never sensitive data like passwords or other personal information. Use standard loggers in any language, but this should be taken care of. Try to ensure that messages are in top-parsable format.

The default stringifier also minifies the JSON, which looks ugly. It can do cool stuff like revive data, use a custom format to encode/decode data, hide certain properties in stringified data, and format your data. Let's dive into some of the cool features.
keycdn·4yAPI Security: The Complete Guide
API security is a crucial consideration when developing and designing APIs. As serverless architectures and microservices are getting more popular, most enterprise applications depend on the API. This attack is detected when a malicious attacker changes or tries to change parameters across a series of API calls to request sensitive data that only authorized personnel are allowed to access.

Medium·3yThe power of TypeScript decorators: real cases. Decorating class methods.
The power of TypeScript decorators: real cases. Decorating class methods. The technology itself can be classified as metaprogramming or declarative programming. Using decorators, we can avoid code duplication by encapsulating a cross-cutting concern in a standalone module.
Bits and Pieces·4yCurrying for JavaScript Developers with Examples
Currying is a way to transform functions that accept multiple parameters into a sequential list of functions that take only one parameter each. The aim of using currying is to give us some syntactic sugar when it comes to calling our logging function. Currying in this case provides several benefits: It helps us make our code more readable by abstracting some of the less important and repeatable values.
Dev Genius·4yDocker security: Risks and Best Practices
The Docker daemon generates and manages your Docker objects, such as images, containers, networks, and volumes. By default, the process inside a container is run as root (id=0) To enforce the principle of least privilege, you should set a default user. Testing should be a part of every development project that considers security.
