Sample text
This is the reason why when we use the @example YUIDoc tag, we indent the code listed alongside it. Simply install Grunt by typing `npm install grunt` at the command line. doctype html>
The example shown produces the following output HTML once processed. Note that any HTML tags have some of their characters replaced with entities so they render as text instead of attempting to parse as the tags they represent. doctype html> <html> <head> </head> </html>Adding Quotes To quote a citation within a paragraph of its own, simply precede the text with a right-facing angle bracket followed by one or more spaces or tab characters.
ECMAScript 5 adds another method, bind, which doesn’t execute the function but rather returns a new function with the context of the function set to whichever object is passed into the first parameter of the call to bind. You may have come across a need for this in your own code, particularly with reference to event handlers. If your event handler function is a method on an object instance, you may have been tempted to use this with your handler to execute another method or access a property on the object instance.
It will also complain if you attempt to use an object literal which has two of the same named properties within it (something that’s tripped me up, personally, before), and also if you attempt to use the delete keyword on a variable or function, instead of on an object property where that keyword is intended to be used. Strict mode will also prohibit the use of eval for executing strings containing JavaScript code, as these might be a security hazard and take the control of your code away from what you write yourself.
