How to resolve assignment?

Question

typescript

Hello everyone

There is an object with this type

private handlers: { [key: string]: Function | Function[] } = {};

next in the method I try to execute the following code

if(Array.isArray(this.handlers[handlerId])) this.handlers[handlerId].push(handler);
 else {
    let handlers = [ this.handlers[handlerId], handler ];
    this.handlers[handlerId] = handlers;
 }

I get these errors



for the line

if(Array.isArray(this.handlers[handlerId])) this.handlers[handlerId].push(handler);

and



on the line

this.handlers[handlerId] = handlers;

How do I tell the compiler that I took care of the type checking myself, or how do I suppress these errors?
