Error: Cannot invoke an expression whose type lacks a call signature

Question

I am brand new to typescript, and I have two classes. In the parent class I have:

abstract class Component {
  public deps: any = {};
  public props: any = {         


        

Answer 1

This error can be caused when you are requesting a value from something and you put parenthesis at the end, as if it is a function call, yet the value is correctly retrieved without ending parenthesis. For example, if what you are accessing is a Property 'get' in Typescript.

private IMadeAMistakeHere(): void {
    let mynumber = this.SuperCoolNumber();
}

private IDidItCorrectly(): void {
    let mynumber = this.SuperCoolNumber;
}

private get SuperCoolNumber(): number {
    let response = 42;
    return response;
};
