How To Use expect.objectContaining With Null and Undefined
I recently came across a workaround for this issue by using the expect.toBeOneOf() matcher from the jest-extended library. This matcher allows you to check whether a value matches one of the expected values, including null and undefined.

Node.js 20 is now available
Yes, a standardized expect would be nice, but care has to be taken to not bloat it.
Currently I use vitest and https://github.com/jest-community/jest-extended which gets you a reasonable amount of usable matchers.

To Review or Not to Review: The Debate on Mandatory Code Reviews
Automating code checks with static code analysis allows us to enforce code styling effectively. By integrating tools into our workflow, we can identify errors at an early stage, while coding instead of blocking us at the end. For instance, flake8 checks Python code for style and errors, eslint performs similar checks for JavaScript, and prettier automatically formats code to maintain consistency.

Git Project Configuration With Husky and ESLint
Letβs walk through the steps for a one-time setup to configure husky pre-commit and pre-push hooks, ESLint with code styles conventions, prettier code formatter, and lint-staged. Husky automatically runs a script on each commit or push. This is useful for linting files to enforce code styles that keeps the entire code base following conventions.

Six Factors That Raise The Risk Of Bugs In A Codebase
1. Lack of Static Code Analysis Static code analysis tools like TypeScript and ESLint play a crucial role in identifying and preventing bugs. TypeScript provides static typing, enhancing the robustness of the code. ESLint detects issues and enforces coding standards. The absence of these tools can significantly elevate the likelihood of bugs due to the lack of early detection and guidance provided during development.
