TypeScript: How to add static methods to built-in classes

Question

Is there anyhow anyway to add some static method to types like Date, String, Array, etc?

For example I want to add method to

Answer 1

I use this code to extend Object with static method. export class ObjectExtensions { }

declare global {
    interface ObjectConstructor {
        safeGet(expresstion: () => T, defaultValue: T): T;
    }
}

Object.safeGet = function (expresstion: () => T, defaultValue: T): T {
    try {
        const value = expresstion();
        if (value != null) return value;

    } catch (e) {
    }
    return defaultValue;
}

In main.ts you have to call this class like this

new ObjectExtensions();

And then you can use it like this:

Object.safeGet(() => data.property.numberProperty);
