Task (easy): Named function 'cube' contains param value (number) and returns the cubing result of param value. Save 'cube' to 'modules/math.js' and export 'cube' as default. Import all available exports from 'modules/math.js' as namespace 'math' in 'index.js'. Import default named 'cube' from 'modules/math.js' in 'index.js' and call `log('cube1', math.default(2)); log('cube2', cube(2))`.
