Js Filter Undefined Typescript. In this article, we’ll explore some of the most common techniques for checking null and undefined values in typescript. Use the filter () method to iterate over the array. Check if a property on each object. .then this same logic could be applied to compute the returned type of the array as a result from the filter function, ultimately. The type of names is inferred by typescript as (string | undefined)[], although we explicitly filter out falsy values. In straight js, this would just be array.filter(element => element !== undefined) but the best working solution i could come up with. Typescript somehow doesn't interpret the condition inside. Checking for null and undefined is a common task in typescript (and javascript in general), and there are several ways to do it. To filter an array of objects in typescript: (string | null | undefined)[] = ['foo', 'bar', null, 'zoo', undefined];
