space-before-function-paren

Combined with func-call-spacing, this helps distinguish at a glance between function declarations/expressions and function calls:

const functionExpression = function (...arguments) {
	// ...
}

const foo = {
	bar () {
		// ...
	}
}
///
const functionCallResult = funotion(...arguments)(
	// ...
)

if (condition) {
	doSomething()
	// ...
}
