Fastest method to replace all instances of a character in a string [duplicate]

Answer 1

Just thinking about it from a speed issue I believe the case sensitive example provided in the link above would be by far the fastest solution.

var token = "\r\n";
var newToken = " ";
var oldStr = "This is a test\r\nof the emergency broadcasting\r\nsystem.";
newStr = oldStr.split(token).join(newToken);

newStr would be "This is a test of the emergency broadcast system."
