Question

What are the drawbacks of dynamic directive arguments?

Answer 1

Apart from the benefits of dynamic directives arguments, it brings two drawbacks or considerations on the usage

1. Constraints on expressions: When you perform complex JavaScript expressions, make sure that html attribute names cannot contain spaces and quotes. The below expression doesn't work as expected

   <div :[key + 'unique']="value"></div>
   Instead you may need to use string template syntax

   <div :[`${key}unique`]="value"></div>
2. Custom Directives: The custom directive implementations need to have potential argument changes in addition to value changes.
