"Enhance your coding experience with Typescript's

Having some issues with autocompletion in my code. I'm trying to implement autocompletion when using a factory class to create objects:

class Test1 {
    method1(){}
}
class Test2 {
    method2(){}
}
class Test_Factory {
    create(type) {
        if (type === "test1") {
            return new Test1()
        } else if (type === "test2") {
            return new Test2()
        }
    }
}
let factory1 = new Test_Factory()
let tst1 = factory1.create("test1")
tst1. // experiencing autocomplete issues

Any suggestions?

When dealing with multiple types in TypeScript, it's important to specify the expected type for proper intellisense functionality. This can be done by casting the return value to the desired type.

let example1 = factory1.create('example1') as Example1;

Alternatively, you can also use the following syntax:

let example1 = <Example1>factory1.create('example1');
