JavaScript

Overview

This skill provides a general overview of JavaScript best practices and guidelines.

• Use early returns whenever possible to make the code more readable.
• Use descriptive variable and function/const names. Only use abbreviations when they are well-known and universally understood.
• Prefer CSS transitions/animations over JavaScript for smoother, GPU-accelerated effects
• Check the code for linting errors and fix them, using eslint and eslint-config-kswedberg if available.

Function Syntax

• Use function expressions instead of function declarations.
• Use named function expressions when you need to use the function name in the function body (e.g. for recursion).
• Use arrow functions for concise anonymous functions.
• Avoid arrow functions ONLY when you need to access a this keyword scoped within the function.
• When returning an object literal, NEVER use the shorthand format. Instead, use curly braces and return the object explicitly.
