Pushing items to an array in typescript with key value

Question

I would like to push an array to another array but the result generates an incorrect result

let pusheditems:any[]  = [];
pusheditems.push(this.yesvalue);
pusheditems.push(this.selectedtruck);

Later when i console.log(pusheditems)

Am getting an array of type

array(0->yes array, 1->select truck array)

What am looking for is to change the index values of 0,1 to strings like yes, truck

So i would expect to get

array(yes->yes array, truck->select truck array)

I have also tried

pusheditems.push({yes:this.yesvalue});  //adding yes
pusheditems.push({truck:this.selectedtruck}); //adding truck

But this doesnt work

The values of

this.yesvalues and this.selectedtruck are also arrays

What do i need to add further

Answer 1

In Typescript, arrays can have keys only of type number. You need to use Dictionary object, like:

    let pusheditems: { [id: string]: any; } = {};    // dictionary with key of string, and values of type any
    pusheditems[this.yesvalue] = this.selectedtruck; // add item to dictionary

Answer 2

Thing you are trying to achieve is to create object, not an array.

You can do it:

let pusheditems = {};
pusheditems[this.yesvalue] = this.selectedtruck;
