Rules

switch-case-braces

Enforces consistent use of braces in switch case statements. Requires braces when lexical declarations (const, let, class, function) are present, and suggests removing braces when they are not needed.

Valid:

switch (value) {
  case "a":
    console.log("a")
    break
  case "b": {
    const x = 1
    console.log(x)
    break
  }
}

Invalid:

switch (value) {
  case "a": {
    console.log("a") // Unnecessary braces
    break
  }
  case "b":
    const x = 1 // Missing braces for lexical declaration
    console.log(x)
    break
}
