Angular4 and TypeScript property does not exist on type any[]

I can't seem to figure this thing out... I'm getting data from an api and storing it as any[]. I'm trying to get data like this...

this.data.results[i].datas[j].dataType

But I get the error property results does not exist on type any[]. I've tried looking at many other questions and answers but I can't seem to figure it out.

(Should I just create a data object and instead of assigning the data to any[], assign it to the object?) Thanks for your help!

I'd always (when possible) at least declare an interface like this:

interface IDataset {
    dataType: string;
    value: string;
    // Whatevery your dataset holds
}

interface IResultset {
    datas: IDataset[9]
}

interface IData {
    results: IResultset[];
}

class SomeClass {
    data: IData[];

    someFunction() {
        this.data.results[i].datas[j].dataType = "whatever";
    }
}

That way you get IntelliSense for your data, have to structure your data in a way that makes sense and could use these interfaces on both client and server side (if you are working on the server too)

You should change the type definition of this.data to:

data: {results?: any[]} = {};
