React Hooks 中未使用的 var

Question

I'm using React Hooks in my SPA. I know how it works, but I have a doubt when declaring the hook, ie, I'm using react-cookie and the declaration of the hook is const [cookies, setCookie, removeCookie] = useCookies([]); .

In my case, I will only need the removeCookie var , I won't use the cookies and setCookie vars in my functional page, so lint complains about unused vars.

Is it possible to ignore these two vars ? I tried const [..., ..., removeCookie] = useCookies([]); but this won't work.

Thanks in advance.

Since you use array destructuring to make the assignments, you can ignore the items by adding commas without the variables/consts names:

const [,, removeCookie] = useCookies([]);

Example:

 const [,, c] = [1, 2, 3] console.log(c)
