Code style without pain: rules, tools and a quick implementation plan

A single style is not about "beautiful", but about speed, predictability and fewer bugs. Below are the arguments, tools, and a plan for implementation without war.

Why do you need a code style?

• Reading speed.

  A single file type removes "visual noise": the brain does not need to get used to different indents/quotation marks, and you understand the logic faster.

• Fewer disputes.

  Formatting is decided by tools (Prettier/Black, etc.), so the architecture is discussed at the review, not spaces.

• Predictability.

  The same file structure (imports, method blocks) reduces the time for orientation in the new module.

• Honest diffs.

  The auto-formatter separates the "cosmetics" from the essence: in PR, only semantic changes are visible.

• Fewer bugs.

  Linters catch dangerous constructs (shadow variables, unused imports, forgotten await) even before startup.

What is included in the code style

• Formatting: indents, quotes, line length, blank lines, hyphenations.

• Naming: functions — verbs, entities — nouns; constants UPPER_SNAKE.

• File structure: the order of imports, blocks of private/public methods, exports.

• Comments and docs: "why" is more important than "what"; doxstrings to public APIs.

• Language idioms: "as usual" in Python/Go/JS/Rust.

Tools that relieve pain

JavaScript/TypeScript

• ESLint + Prettier (and for CSS — Stylelint)

• Hooks before commit (husky/lefthook): auto-run formatter

Python

• Black or ruff format, plus isort

• Optional — mypy for types

Go

• gofmt/goimports — built-in standard

• golangci-lint — fast general lint

Rust / Kotlin / Java

• rustfmt + clippy

• ktlint/spotless, Checkstyle

Put the general settings in .editorconfig and the checks in CI. Then the "wrong" code simply will not pass.

Was → became

JavaScript

// Before
function getuser(a){ if(!a){return null;} return { name:a.name , age:a.age} }

// Now
function getUser(user) {
  if (!user) return null;
  return { name: user.name, age: user.age };
}

Python

# Before
def calc(a,b):return a+b

# Now
def calc(a: int, b: int) -> int:
    return a + b

It is a good illustration of the automation and CI section.

A unified code style is the foundation of team speed and quality. Adopt the standard, automate checks, and fix the rules in the repository — and you will only have to discuss the architecture, not the gaps.

Question to you: What causes the most controversy in your team — quotation marks, line length, or import order?
