You cannot call this expression. The data type 'Boolean' does not have any callable signatures

As I delve into learning a new set of technologies, encountering new errors is inevitable.

However, there is one particular type of error that keeps cropping up, making me question if I am approaching things correctly.

For instance, I consistently face this error with Vue components:

Property 'focused' does not exist on type '{ onInput(event: any): void; focus(): void; blur(): void; }'. Did you mean 'focus'?

blur(): void {
  this.focused = false
}

I usually resolve this issue by using a similar approach:

blur(): void {
  (this as any).focused = false
}

It's puzzling that I have to implement this workaround in every component and at every occurrence.

Furthermore, I'm stuck on trying to tackle the following error:

This expression is not callable. Type 'Boolean' has no call signatures.

blur(): void {
  (this as any).l.focused = false
}

It seems to be pointing towards "false."

The code for data():

data(): any {
  return {
    l: {
      focused: false
    }
  }
},

If you have any insights on how to properly handle these types of situations, I would greatly appreciate your advice.
