Created December 10, 2018 15:58

A simple example of passing multiple ports into a node process to be captured as process.argv[2]

	// sh
	# In one terminal window
	$ node server/index.js 8082
	listening on port 8082

	# In a different terminal window
	$ node server/index.js 8083

stephencweiss / JS - custom sort multi-condition

Created December 10, 2018 15:14

Example of multiple condition sort method for a nested array -- sorts numbers descending then letters ascending (in event of tie)

	const nestedArray = [ [ 'm', 1 ], [ 'i', 4 ], [ 's', 4 ], [ 'p', 2 ] ];

	function descNumbersAscChar(arrA, arrB) {
	if (arrA[1] > arrB[1]) { return -1 }
	else if (arrA[1] === arrB[1]) {
	if (arrA[0] < arrB[0]) { return -1 }
	else if (arrA[0] > arrB[0]) { return 1}
	}
	else if (arrA[1] < arrB[1]) { return 1 }
