Write a javascript function called countRegNumber that takes in a string parameter that looks like this 'CA 182736,CY 523519,CJ 812328' and returns the number of registration numbers in the string.

It should also work for this string 'CA 42665, AA 12 RT GP'. Test it with some strings of your own. Use Strings builtin split function. And List objects length function. These asserts should pass: var regCount = countRegNumber('CA 182736,CY 523519,CJ 812328') assert.equal(regCount, 3)

These asserts will test your function:

var regCount = countRegNumber('CA 182736,CY 523519,CJ 812328') assert.equal(regCount, 3);

var regCount = countRegNumber('CA 182736') assert.equal(regCount, 1);
