Coderbyte: Have the function SwapCase(str) take the str parameter and swap the case of each character. For example: if str is "Hello World" the output should be hELLO wORLD. Let numbers and symbols stay the way they are.

swapCase.js

//coderbyte

function SwapCase(str) { 
	var newChar='',
	newString='';

	newString = str.replace(/./g, function(myChar){

		//use the replace to iterate and rebuild string
		if (myChar.match(/[a-z]/)){
			newChar=myChar.toUpperCase();
		} else if (myChar.match(/[A-Z]/)){
			newChar=myChar.toLowerCase();
		} else {
			newChar=myChar;
		}

		return newChar;

	});

	return newString; 
         
}

Thanks dear ...
