StdDev is a micro-library written in CoffeeScript (and includes generated JavaScript versions) that computes the standard deviation for an array of numbers.
stdev = stddev [7, 2, 8, 2, 4, 25, 9, 9, 4, 9]
console.log stdev # 6.640783086353596 var stdev = stddev([7, 2, 8, 2, 4, 25, 9, 9, 4, 9]);
console.log(stdev); // 6.640783086353596bower install stddev- download the zip

gulp lintwill lint source code for syntax errors and anti-patterns.gulp gpawill analyze source code against complexity thresholds.gulp testwill run the jasmine unit tests against the source code.gulp test-coffeewill run the jasmine unit tests against the CoffeeScript source code.gulp test-minwill run the jasmine unit tests against the minified code.
