Add a property to the type of an Array typescript-CodePudding

Working on a chat app, I encountered a problem trying to add a property to the array of object.

    // original array 
    const authors: User[]  = []
    //But I wanted to add something like this
    const authors: User[] & { otherProperty: string }[]  = []

I thing I could extend the array outside and then make it an array, but it is posible to do it with an intersection? I'm honestly curious

CodePudding user response：

You want to add the property to User right?

const authors: (User & { otherProperty: string })[] = [];
