类型 Posts[] 上不存在属性查找

Question

I created the following interface:

export interface Post {
    _id: string;
    admin: Admin;
    comments: PostComment[];
    createdAt: Date;
    modified: boolean;
    text?: string;
    desc?: string;
    photoPath?: string;
}

But when I used this:

const post = posts.find((e: Post) => e._id === cmnt.postId);

it throws error, 'Property 'find' does not exist on type 'Post[]'.. How to fix this...

You need to set your compiler target to ES6 in tsconfig.
