Learned today that you can skip items when destructuring an array by using commas and leaving the index you want to skip over blank. This can be really helpful for certain api responses that are structured in an array, but you only want the second item.
For example:
const response = [responseInfo, body, error];
const [, body] = response;
In this destructuring we only want the second item from the array. Doing this will avoid linting errors from unused variables just to get to the index you wanted.
