Define Lines in a String

You know that to define a String in Java Script requires that you enclose the data within quotes. For example, the statement below displays a string (the first line in Abraham Lincoln's in the Gettysburgh address) in a message box.

alert("Four score and seven years ago our fathers brought forth on this continent, a new nation, conceived in Liberty, and dedicated to the proposition that all men are created equal.");

(code required to be on one line.)

Message box too wide

As you can see above, this creates an unappealing too wide message box. We can improve the aspect ratio of the message box by placing newline \n character escape sequences within the string to explicitly define where the string should break to create a new line, as shown below.

alert("Four score and seven years ago our fathers\n brought forth on this continent, a new nation,\n conceived in Liberty, and dedicated to the\n proposition that all men are created equal.");

(code required to be on one line.)

More appealing message box

This creates the more appealing message box shown above.

If you want to format your code so that it has the same line structure as that displayed in the message box, enclose each line in quotes and use the string concatenation operator to rejoin the lines, as shown below.

alert("Four score and seven years ago our fathers\n" + "brought forth on this continent, a new nation,\n" + "conceived in Liberty, and dedicated to the\n" + "proposition that all men are created equal.");

This makes your code more neat and more understandable.
