eslint/curly Style

🛠️ An auto-fix is available for this rule.

What it does

This rule enforces the use of curly braces {} for all control statements (if, else, for, while, do, etc.). It ensures that all blocks are enclosed in curly braces to improve code clarity and maintainability.

Why is this bad?

Omitting curly braces can reduce code readability and increase the likelihood of errors, especially in deeply nested or indented code. It can also lead to bugs if additional statements are added later without properly enclosing them in braces. Using curly braces consistently makes the code safer and easier to modify.

Examples

Examples of incorrect code for this rule:

if (foo) foo++;

for (let i = 0; i < 10; i++) doSomething(i);

while (bar) bar--;

Examples of correct code for this rule:

if (foo) {
  foo++;
}

for (let i = 0; i < 10; i++) {
  doSomething(i);
}

while (bar) {
  bar--;
}
