There are several ways, but if you may have \r or \n, I'd probably use replace with a regex:

str = str.replace(/(?:\r|\n).*$/, '');

use regex:

var str = "First Line" + "\n Second Text Line";
var line = str.replace(/(?:\r|\n).*$/, '');
console.log(line);

split string using a "\n" as a delimeter and then join the string back together

var strings = str.split("\n");
var finalstr =strings[0];
