Top Highlights

• Code first, then functions
• Linters are tools that can automatically check the style of your code and make improving suggestions.
• Insert an extra newline where it helps to make the code more readable. There should not be more than nine lines of code without a vertical indentation.
• the opening brace on the same line as the corresponding keyword – not on a new line. There should also be a space before the opening bracket
• For a very brief code, one line is allowed, e.g. if (cond) return null. But a code block (the last variant) is usually more readable.
