StackBlitz - Property entries does not exist on type 'ObjectConstructor'

Question

I am trying to use this syntax in StackBlitz:

const someObject = {};
for (let [key, value] of Object.entries(someObject)) {
   // .... do whatever
}

The editor is underlining the entries in red and stating that "Property entries does not exist on type 'ObjectConstructor'".

However the code is still working. It seems to just be a linting issue where the editor thinks this won't work... but it does.

here is the stackblitz if someone could help https://stackblitz.com/edit/angular-validation-errors

How can I get the editor to know the language properly?

我发现 Stackblitz 不知道你正在使用哪个版本的 TypeScript。默认情况下 babel 的目标是 es5 规范，但据我所知Object.entries是在 es2017 中添加的。

要解决您的问题，只需将其添加到名为“输入包名称”的输入中的“依赖项”部分中

npm i typescript

或者

typescript
