What it is
Clean Code JavaScript is a guide to JavaScript readability. It adapts Clean Code ideas to functions, arguments, objects, classes, async code, error handling, and tests.
The project is useful because it shows contrast: a problematic example next to a cleaner one. That makes it easier to see why names, flag arguments, or hidden side effects hurt maintainability.
What is inside and how people use it
Inside is a Markdown document with sections and JavaScript snippets. It is not a language standard or linter, but material for review, training, and code-quality discussions.
Function naming
This example shows a basic idea: the name should say what the function does.
// хуже
function handle(data) {
return data.filter(item => item.active)
}
// лучше
function getActiveUsers(users) {
return users.filter(user => user.active)
}A typical use case is applying one section to real code: reduce argument count, name functions by intent, remove flags, and isolate error handling.
Strengths and limitations
The strength is simplicity and specificity. The repository helps discuss code quality through concrete examples rather than vague rules.
The limitation is that general advice should not be applied mechanically. Sometimes performance, compatibility, or local style matters more than a perfect example.
