Follow consistent formatting and syntax patterns to improve code readability and maintainability. This includes using compact formatting for test blocks, proper quote usage, positive-first conditionals, and preferred syntax patterns. Key formatting guidelines: - Use compact formatting for describe/it blocks: `describe('errors', { defaultCommandTimeout: 50 }, () => {` - Prefer double quotes over escaped single quotes: `"foo"` instead of `'foo\'` - Put positive conditions first in if statements: `if (state.initialBuildSucceed) { ... } else { ... }` - Use direct return expressions: `return (expression)` instead of `if (...) return true` - Prefer `.catch()` syntax over try/catch blocks for promise handling - Use proper eslint disable patterns: `/* global jest */` at file top instead of inline `eslint-disable-next-line no-undef` These patterns make code more readable and follow modern JavaScript conventions while reducing cognitive load for developers.
