Svelte5 : Support for bracket notation in dynamic component rendering

[HitoshiroKyoka]

Describe the problem

I would like to propose a feature to support bracket notation for rendering dynamic components. Currently, only dot notation is supported, but adding support for bracket notation would provide more flexibility.

example:
Svelte Lab

While dot notation is useful for static keys, bracket notation would provide more flexibility for dynamic keys and expressions.

Describe the proposed solution

Allow the use of bracket notation to access and render components from an object, similar to how it works with other JavaScript objects. For example:

<components[key]></components[key]>

I think this has been rejected.

Correct, we'll not add this capability. Using $derived in the script or @const in the template to prepare the component should be easy enough for this somewhat uncommon case.
