Please what does the split('0') do in this code

Object.assign takes two arguments in this case.

The first argument is the target (to which properties will be assigned), in this case Array.prototype
The second argument is a source (from which to assign properties), in this case the methods specified in the instructions (square, cube, sum, etc)

The properties (methods) from the source are applied to the target, and the target is returned. In this case the return value is not necessary but the target ie: Array.prototype is modified (mutated).

This is how many libraries like lodash and others work, "under the hood".

Like this a lot. Brilliant

superb man , it is good to understand too. I manually made it binary but no worries it took me just 5mins

gerat!

Fascinating

someone explain please

i was confuzzled on this problem for an entire month
when i solved it in 7000 lines of code only to see this
i just quit

great solution mate, can anyone tell me that, One line solution is better or mine is better?
i can write in one line but i think mine is more easy to understand, is spliting one line code to 2 or more is a bad habbit?

I love it, so clever 😁
