解析错误:意外的令牌...
老实说,我不明白为什么ESlint会为第一个console.log
语句而不是第二个语句添加错误:
const generateCss = () => {
console.log({...{foo: 'bar'}});
};
function bar() {
console.log({...{foo: 'bar'}});
}
有什么解释吗?或者是我的错?
ESlint(v7.2.0)配置:
{
"extends": "eslint:recommended",
"env": {
"es6": true,

"mocha": true

正如在对答案的评论中提到的那样,对象传播在ES2018中引入。
因此,如果您使用的是更现代的ES功能,请记住为此在配置中更新"ecmaVersion"
。在这种情况下,您需要"ecmaVersion": 9
。
完整列表如下:
ES3 -> 3
ES5 -> 5
ES2015 -> 6
ES2016 -> 7
ES2017 -> 8
ES2018 -> 9
ES2019 -> 10
ES2020 -> 11
