JS传播和休息运算符的运算符优先级？

Question

I'm curious what the precedence of the Spread and Rest operators are in Javascript: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Spread_operator

I was trying to find them on MDN's Operator Precedence table ( https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Operator_Precedence#Table ) but unless they are a subcategory of an existing operator type, I don't see them. I couldn't find any other obvious documentation about it.

Answer 1

Spread syntax is not an operator and therefore does not have a precedence.

It is part of the array literal and function call (and object literal) syntax.

Similarly, rest syntax is part of the array destructuring and function parameter (and object destructuring) syntax.
