I know, just saying is not best practice to use it. Have a great day and happy coding :)

nice solution, although using eval is not recommended for security reasons.

"for" loops are the fastest. Any other function does that internally anyway.

I managed to do it in the end ! very nice kata. I learnt a lot ! Well done guys !

How can size property be not enumerable, writable nor configurable ?
I was able to change the value of property size when writable = false && configurable = true OR writable = true && configurable = false.
If they are all false there is no way to change the value of the property size. Am I missing something? Any suggestion?
Thank you !

same problem here, I dont know what to do. anyone can help us? haha

Hey, I was wondering if it is possible to use jQuery methods.
I'm cloning my objects using "jQuery.extend(true, {}, vectorToClone);"
but it is not allowing me.

This is the best solution for me. Well done ^^

For me it's not clear when the function should count the number of integers or characters, and when count the number of the occurrence for a string given.

In this call countCombinations('93049', '\d'); , what happens if I call it like :
countCombinations('93049\d', '\d');
Should it return 1 ? or 5? or 6 ?
Same issue with countCombinations('Five ', '.'); for characters

Unless "\d" and "\d" are keywords to know what to do in each case. Otherwise Im confused!

Thanks ! ^^
