The latest TypeScript version also introduces improvements for working with arrays and promises Credit: Thinkstock TypeScript 3.6, the latest version of Microsoft’s typed superset of JavaScript, is now available as a production release. It brings stricter checking of iterators and generators and ...
With TypeScript 2.6, we’re introducing a new--strictmode flag:--strictFunctionTypes. TypeScript has traditionally compared parameters in a bivariant manner. There are a number of reasons for this – modeling event handlers in the DOM, allowing a simpler model for working with arrays, and more...
Tuple types allow TypeScript to begin typing the new patterns we will see in the upcomingECMAScript 6 standard, where new features like array destructuring allow developers to work with arrays in richer ways. Tuple types have the advantage that now you can accurately describe the type of an ar...
however, TypeScript can't deduce things that I know to be true. For example, when working with Arrays, TypeScript believes that the Array methods .shift() and .pop(
Conclusion ngForis a powerful directive in Angular that allows you to display collections of data in a flexible and efficient way. Whether you're working with arrays, objects, or other collection types,ngForhas you covered.

There are advantages to working with arrays instead of structs (in which case you should use gl-matrix) but structs may feel more user-friendly in an application and may interop more easily with 3rd party libs like three.js. Plain objects may (in some cases) be faster than arrays. Using...
