eslint - 在我的 vue 项目中使用数组解构

Question

I have a line like this this.report = newVal[0]; . I'm looking at the documentation and I'm confused.

example I have seen are like

const local = this.propslocal
const {local} = this.props

any ideas?

Answer 1

Take a look at this: eslint prefer-destructuring rule :

This rule enforces usage of destructuring instead of accessing a property through a member expression.

As the examples you have seen, you should change your:

this.report = newVal[0]

To this instead:

[this.report] = newVal;

To make it clear for you, if newVal has 4 items, and you want to store first 2 items into different variables, instead of doing:

const a = newVal[0];
const b = newVal[1];

Using destructuring, you should do:

const [a, b] = newVal;
