Array of arrays of interfaces

Question

I can do this:

result: MyInterface[] = [{prop1: val, prop2: val}]
result2: MyInterface[] = [{prop1: val, prop2: val}]

totalResult = [
 this.result,
 this.result2
]

this gives me [][], the question is how to merge this initialization into creation result and reusult2 inside totalResult and telling that totalResult is array or arrays of MyInterface ?

Do you mean totalResult: MyInterface[][] = ...?

You can do it like this

result: MyInterface[] = [{prop1: val, prop2: val}]
result2: MyInterface[] = [{prop1: val, prop2: val}]

totalResult = [
 ...this.result,
 ...this.result2
]

this will add all your item of result and result2 in one array

that's if you want a simple array, if you want an array of array just do it like this

totalResult.push(this.result);
totalResult.push(this.result2);

EDIT after comment :

if you want to avoid result and result 2 do it like this

totalResult : Array<MyInterface[]> = [[{prop1: val, prop2: val}], // result
[{prop1: val, prop2: val}]]; // result2

Keep the type for totalResult too, so that you will get clear picture. you can do it like below. [ Array of Arrays of your interfaces ]

result: MyInterface[] = [{prop1: val, prop2: val}]
result2: MyInterface[] = [{prop1: val, prop2: val}]

totalResult: Array<MyInterface[]> = [];

this.totalResult.push(result);
this.totalResult.push(result2);
