Introduction to Strongly Typed Code

Explore the concept of strongly typed code using TypeScript within Angular and NgRx. Learn how defining explicit data types enhances error detection during development, ensuring your application handles data correctly and functions as expected in production.

We'll cover the following...

In the example above, we have both loosely typed JavaScript and strongly typed TypeScript code of the same function sum(). The only difference between the two code snippets is the type declarations in the TypeScript ...
