ITSOverwrite

export interface A1
{
    s: string
}

export type A2 = ITSOverwrite<A1, {
    s: number,
}>
export declare let a2: A2;
// a2.s is number

ITSOverwriteReturnType

import { ITSOverwriteReturnType } from '..';

declare function f(a: number): number

declare let c: ITSOverwriteReturnType<typeof f, string>;
// c is (a: number) => string
// c(1).toUpperCase()

Promise / Bluebird / PromiseLike

npm install @types/bluebird ts-type

export declare function p1(a: number): Promise<number>

export declare let p1_v: ITSUnpackedReturnType<typeof p1>;

p1_v.toFixed()

export declare let p2: ITSWrapFunctionPromise<typeof p1>;
export declare let p3: ITSWrapFunctionBluebird<typeof p2>;
export declare let p4: ITSWrapFunctionBluebird<typeof p1>;

p2(1).then(v => v.toFixed())
p3(1).then(v => v.toFixed())
p4(1).then(v => v.toFixed())

this

export declare function t1(this: string, a: number): Promise<number>

export declare let t1_this: ITSUnpackedThisFunction<typeof t1>;

// => t1_this is string

export declare function t2(this: string, a: number): number

export declare let t3: ITSOverwriteThisFunction<number, typeof t2>;

t3 = function ()
{
    this.toFixed() // => this is number

    return 1
}

interface Function2 extends Function
{
    bind<T extends any, F extends (...args: any[]) => any>(this: F, thisArg: T, ...argArray: any[]): ITSOverwriteThisFunction<T, F>;
}

export interface t4 extends Function2
{
    (): string
}

export declare let t5: t4

export let t6 = t5.bind([] as string[])

t6 = function ()
{
    this.includes('') // => this is string[]

    return ''
