Get item by another element from list in TypeScript

Hello,

Type Script in Ionic2 application:

How to get item from this.myList of check-boxes by another element. If I add elements to private myList: any = []; this way:

  this.myList.push({ id: i, name: myName, UID: obj.UID },);

where id: i is a loop iteration number, name: myName is a username, and UID: obj.UID is a non sequential specific number, then myList content should be:

    id| myName   | UID
    -------------------
    0 | sally    | 345
    1 | vikram   | 5487
    2 | kim      | 12
    3 | roy      | 2134

Goal is to find ID: obj.ID by myName value. For example get UID value: 12 by myName: kim

it is undefined and does not returns existed value, this way :

findByName() {
    const found = this.myList.find(({ name }) => this.searchName === name);

    if (found) {
        return found.UID;
    } else {
        return null;
    }
}

then I’ve tried differently, with adding: this.myList[myName] = { id: i, name: myName, UID: obj.UID }; to list: myList: {[name: string]: { id: number, name: string, UID: string }} = {}; but it same result undefined:

findByName(searchName: string) {
    const found = this.myList[searchName];

    if (found) {
        return found.UID;
    } else {
        return null;
    }
}
