Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

Friendly URLs

By default, Rails applications build URLs based on the primary key -- the id column from the database. Imagine we have a Person model and associated controller. We have a person record for Bob Martin that has id number 6. The URL for his show page would be:

/people/6

But, for aesthetic or SEO purposes, we want Bob's name in the URL. The last segment, the 6 here, is called the "slug". Let's look at a few ways to implement better slugs.

	#Create a directory to hold the application. Lets call the application rail

	$ mkdir rail
	$ cd rail

	# Now we’ll initialise a npm project. Use the following command for initialising. This command will create package.json file in the directory which will hold information about rail package and its dependency and meta data.
	$ npm init

	# Next task is to install express for this project. Don’t forget to use — save which adds Express as a dependency in package.json.
	$ npm install express — save

	// As per the question I am assuming that 1,3,4 should appear together anywhere in the array of numbers

	arr = [-1, 0, 1, 3, 4, 7, 9]
	'134' in ''.join(map(str, arr))
