如何解构此数组？

Question

ESLint recommended me to destructure below array to ES6 style(prefer-destructuring). Is it possible to destructure this?

params[key] = params[key].split('?')[0];

Answer 1

With array destructuring, you put the left-hand side in [...] where each element corresponds to the element you want from the right-hand side. In this case, you just want the first element, so:

[params[key]] = params[key].split('?');

Live Example:

 const params = { foo: "foo?bar" }; const key = "foo"; [params[key]] = params[key].split('?'); console.log(params[key]);
