You&#8217;ll learn how TypeScript provides powerful tools to manage these values, including strict null checks, union types, optional chaining, and nullish coalescing. With strict null checks enabled, TypeScript ensures that null and undefined are only used where explicitly allowed, reducing errors and improving code safety.<\/p>\n<p>By the end of this tutorial, you&#8217;ll understand how to safely handle nullable types in TypeScript, ensuring your code is more resilient and reliable.
