Script Preparation code:

var shortString = "Short string without newline";
var longString = "This is a very long string that represents a large amount of text data potentially copied from a web upload form. It does not contain any newline characters initially but we want to check the performance impact of running a regex replace vs a simple indexOf check.";
var longStringWithNewline = longString + "\n" + longString;
var regex = /\r\n|\n/;

Tests:

_.replace
_.replace(longString, regex, '');
.indexOf(/n)
if (longString.indexOf('\n') > -1 || longString.indexOf('\r') > -1) { longString.replace(regex, ''); }
