Property 'title' does not exist on type 'unknown'.

how to fixe it

[johnsoncodehk]

This is expected, you need to define value type correctly.

value: {
  type: Array as PropType<{ title: string }[]>
}

This is a JS file and not a TS
Is there any other plan?

[ci010]

Do you mean we should disable part of typecheck function for js script by default?

[anyclub]

typecheck is very helpful most of the time, but if my project cannot use TS, similar situations may happen from time to time.
It is recommended to have a disable check switch for the value passed in PROPS,
or similar to eslint use injection /* eslint-disable */ /* eslint-enable */ ......

@ts-ignore is available in template:

{{
  // @ts-ignore
  item.title
}}

Please wait for vuejs/core#1359, we can use (item, index) in value as { title: string }[] to resolve after vue supported TS in template.

use jsdoc?

@type {import('@vue/runtime-dom').PropType<any[]>}
type: Array
