The JavaScript language performs automatic semicolon insertion at the end lines, so creating multiline strings usually ends up looking something like this:
var multiStr = "This is the first line" + "This is the second line" + "This is more...";
String upon string of concatenated JavaScript mess...ugly, slow, and ...ugly. Many novice JavaScript developers don't know that there's a better way to create multiline strings:
var multiStr = "This is the first line \ This is the second line \ This is more...";
Adding a backslash at the end of each line tells the JavaScript engine that the string will continue to the next line, thus avoiding the automatic semicolon insertion annoyance. Note that the second string includes line breaks within the string itself. Just another nice tip to add to your JavaScript arsenal!
