Rule: increment-decrement

Enforces using explicit += 1 or -= 1 operators.

Rationale

It’s easy to type +i or -i instead of –i or ++i, and won’t always result in invalid code. Prefer standardizing small arithmetic operations with the explicit += and -= operators.

Config

If no arguments are provided, both pre- and post-unary operators are banned. If "allow-post" is provided, post-unary operators will be allowed.

Config examples

"increment-decrement": true

"increment-decrement": [true, "allow-post"]
