Exercises

Use partial or bind

You can often use more general functions to define more specific functions.

• Define function power(exp, n), the same as Math.pow(n, exp) but with reverse order of arguments.
• Implement function square(n) which returns a number to the power of two.
• bind() function power(exp, n) to obtain function cube(n).

Use closure

Use constructor-like function that returns a function to define different specific functions.

Use lambdas (arrow functions)

Use nested functions for functional inheritance.

Use bind

Use method bind() to existing function to apply preceding arguments and obtain a new function.

Use curry

Given function someFunc() which accepts n arguments (e.g. 3 arguments). Implement function curry() that generates other function which accepts someFunc() arguments partially and supplies them to someFunc():

const func = curry(3, someFunc);

func(a)(b)(c) === someFunc(a, b, c) // true

func(a, b)(c) === someFunc(a, b, c) // true

func(a)(b, c) === someFunc(a, b, c) // true

Exercises

Implement one-argument function that passes its argument to another function and returns an object which has the same function:

func(a).func(b).func(c) === someFunc(a, b, c) // true
