Best Practice
Always use a linter like ESLint alongside a formatter to catch logic errors that formatting alone won't fix.
Did You Know?
TypeScript is a superset of JavaScript, meaning all valid JavaScript is technically valid TypeScript.
JavaScript is the primary scripting language of the web, enabling interactive user interfaces. TypeScript is a powerful superset of JavaScript that adds static typing, making it easier to build and maintain large-scale applications. Because both languages use complex nesting and asynchronous patterns, consistent formatting is essential to avoid 'callback hell' and ensure that the code's intent is clear to all developers on a team.
Tip
Use semicolons consistently to prevent rare but annoying ASI (Automatic Semicolon Insertion) bugs in JavaScript.
For a professional development environment, it is best practice to use formatting tools directly in your editor. Extensions like Prettier or ESLint for VS Code can format your files automatically on save. For teams, adding a formatting check to your CI/CD pipeline ensures that no unformatted code ever reaches your main branch, maintaining a high standard of code quality across the entire organization.
