What is the difference between routerLink and [routerLink] in Angular?

    I'm working on routing in an Angular application and noticed that both routerLink and [routerLink] are used for navigation. However, I'm confused about when to use each and what the actual difference

    <a routerLink="/home">Home</a>

    <a [routerLink]="['/user', userId]">User Profile</a>



    In what scenarios should I use routerLink vs [routerLink]? What is the underlying difference between the two in terms of how Angular processes them?

    I initially used routerLink="/user/1" to navigate to a user profile page, and it worked fine for static routes. But when I tried to make it dynamic like routerLink="/user/{{userId}}", it didn’t work as expected.

    Then I saw examples using [routerLink]="['/user', userId]", which worked. I was expecting both to behave similarly since they are both used to define routes, but the outcomes were different. I'm now trying to understand why [routerLink] works for dynamic values but plain routerLink does not.
