fkill VS ESLint

Generally, npm libraries installed globally aren't standard library you'd use in your programs but more like CLI tools or full blown programs. As an example, fkill is the first one that comes to my mind.

fkill - Fabulously kill processes. Cross-platform.

If you're a developer, you're surely familiar with Prettier and ESLint. With over 8 years of existence, they have established themselves as references in the JavaScript ecosystem.

eslint is used to avoid code errors

No lint errors: The committed code does not contain any lint errors (eslint).

Let’s 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.

ESLint: A pluggable and configurable linter tool for identifying and reporting on patterns in JavaScript.

ESLint

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.

The industry standard for JavaScript is ESLint. VS Code has an ESLint extension. Here is a guide.

All modern linters incorporate functionality for extending configurations, although the syntax for this is often implemented differently. Taking ESLint as an example, in its latest versions, the primary extension method is through the use of the spread operator. Let's take a look at an example:
