What is the most effective design pattern for managing constant strings in Typescript or Javascript?

In my current project, I have implemented a view that can switch between two modes: view mode and edit mode. With the use of Angular directives, I am able to modify the behavior of the page depending on the selected mode. In C programming, it is common practice to #DEF some constant strings for future reference. I am curious if there is a similar design pattern in JavaScript that I could utilize. For instance, I plan to implement something like:

    <input ng-if="mode==='edit'"></input>

Take note of the string literal 'edit'

Answer №1

Utilizing enums, as Satpal proposed, can be a valuable addition to TypeScript. Nevertheless, in your specific scenario, I recommend simply using a boolean within your component (or potentially a service if the mode is utilized throughout the entire app).

Moreover, your HTML code can be much more streamlined, like so:

<input ng-if="editMode"></input>
