If Without Curly Braces

Check if if statements are missing curly braces, even when they contain only one line of code.

📖 What does this rule enforce?

This rule ensures that all if statements, regardless of the number of lines they contain, use curly braces {} to enclose the code block.

❓ Why it's good to follow this rule?

• Readability: Curly braces make the structure of the code clear, reducing the likelihood of misunderstandings. Even if the if statement has only one line, using braces ensures that the code is easy to read and follow.
• Consistency: Enforcing curly braces for all if statements helps maintain a consistent coding style throughout the project, making the codebase easier to navigate.
• Maintainability: Code changes often, and what starts as a one-line if statement can easily grow into something more complex. If braces are already in place, adding new lines of code becomes less error-prone.
• Avoiding Bugs: Omitting braces can lead to subtle bugs, especially when additional statements are added later. With braces, there's no ambiguity about which statements are controlled by the if.

😱 Examples of code for which this rule will throw a warning

WARNING

The following code omits curly braces in the if statement:

if (condition)
  doSomething()

🤩 How to fix it?

TIP

Always use curly braces to enclose the code block within if statements, even if it's just one line.

if (condition) {
  doSomething()
}
