Typescript: calling static methods in constructor [duplicate]

Question

here is an example of my class with the methods in question

class Example {
    constructor(info) {
        // call validateInfo(info)
    }

    static validateInfo(info):void {
        // validate the info
    }

I would like to call validateInfo in the constructor, but I can't just do this with this.validateInfo(info) because it is a static method.

In Javascript, I could do this:

    constructor(info) {
        this.constructor.validateInfo(info)
    }

but, in Typescript this gives the following error:

error TS2339: Property 'validateInfo' does not exist on type 'Function'.

I understand the error message, but is there a Typescript equivalent for the Javascript solution?

The problem is that a subclass may have called the constructor, not Example. I'd reference Example specifically:

constructor(info) {
    Example.validateInfo(info)
}

Another option to consider would be making it a normal method rather than a static method.
