Check if array of strings matching all interface properties

I have an array of strings that has to match an interface properties names

export interface MyType1 {
  propName1: number;
  propName2: string;
  propNameX: number;
}

tableColumns: string[] = [
  'propName1',
  'propName2',
  'propNameX'
];

Initially I was thinking to convert an interface to an array of strings but haven’t found a solution that works.

So now I am wondering if there anyway to see if array of strings matching an interface or something like that.

I’ve tried using https://github.com/kimamula/ts-transformer-keys but it won’t work in my case as I have no access to webpack configuration, otherwise throwing compiled error in the browser.

Need help.

>Solution :

Quite simply

const tableColumns: (keyof MyType1)[] = [
  'propName1',
  'propName2',
  'propNameX'
];
