Could you solve the last LeetCode problem? 🤓 Here's another one, the simplest of the simplest. But hey, we all have to start somewhere.

Starting point

Write a functioncreateHelloWorld. It should return a new function that always returns"Hello World".

My Submission

Let's take a look at my code. Yours maybe looks different, and that's okay. Everyone has their own approach.

varcreateHelloWorld=function(){returnfunction(){return"Hello World"}}

What happens here?

varcreateHelloWorld=function(){}

What was given by LeetCode was the outer declaration, the initialization ofvar createHelloWorld, which was assigned a function.

👻Note: I personally never usevar when declaring a variable, I always opt forlet orconst, but since this was the default, I'll keep it that way (there's nothing really wrong with usingvar).

Return a function

In the description it is said that we should return a function, which I did by writing

returnfunction(){}

Always return "Hello World"

By adding

return"Hello World"

inside the function, the string"Hello World" will be returned, no matter which argument the function may get.

In general, I am bad at explaining technical stuff. So any advice is welcome to improve my explanation skills 🙏🏽.
