How to split a string in equal halves

Question

I'm trying to simulate a simple evolution thing using binary code. Each individual in the "gene pool" has their own unique string in binary code.

In order to have them mate, I need to take half of one string, and the other half of another and merge them. The problem is, I don't know how to split a string in two equal halves, and they are totally random.

Help would be appreciated, thanks!

Answer 1

Well I would get the total length of the string and get the first half by doing

myString.slice(firstIndex, secondIndex)

I would make the firstIndex be 0 and the secondIndex equal to myString.length / 2. That will return the first half of the string.

The second half of the string would be

myString.slice(myString.length / 2, myString.length)

So, all together:

const partOne = myString.slice(0, myString.length / 2)
const partTwo = myString.slice(myString.length / 2, myString.length)
