If you are learning Javascript or functional programming write your own implementation of a curry function could be an interesting way to better understand this technique.

currying is the technique of translating the evaluation of a function that takes multiple arguments(or a tuple of arguments) into evaluating a sequence of functions, each with a single argument. — wikipedia

Let’s think about what we need:
1- A function that will receive another function to curry.
2- return another function that will ask for 1 or more arguments for the original function, this function should somehow save all the arguments it received while the…

Today we are going to talk about these 3 global Objects (functions) in JavaScript and how to use them as factory functions to coerce different values.

Important:

• In JavaScript functions are Objects too. Boolean, Number and String are functions.

• Coercion is when a conversion from one type to another occurs.
• You need to understand the differences between a factory function and a constructor function in JavaScript before you continue reading.

You can use Boolean, Number and String as:

Constructor functions (Bad)

If we use them with the new keyword then we will always return an object - not what we expected:

This…
