Dates are an integral part of almost every application. Angular provides a date pipe out-of-the-box. The date pipe allows users to convert dates according to predefined or custom Angular date formats. For example:

Using it today is disadvantageous because we load a bunch of code when we can probably…

Now let’s say we need to update our interface and add a new property:

We won’t get any Typescript errors in this case, which can lead to bugs in our application. A safer option is always to type the variable explicitly:

In Typescript, Record is a common way to express an object type. For example:

The disadvantage of using a Record in some cases is that you lose the benefit of expressing the meaning of the key. Let’s take the following example:

Looking at this code, I can’t know…

I like to have a types file for each package that manages the types related to it for my applications. With Typescript namespaces, we can create a clean and well-organized types file.

For example, if we have a todos package in our application, we’ll create a todos.types file:
