Made functions return Number<\/code> rather than String<\/code><\/p>\n<\/li>\n- \n
Now all functions are almost pure functions (don’t cause side-effects other than logging)<\/p>\n<\/li>\n
- \n
Formatted numbers prior to printing them by rounding them to the second decimal<\/p>\n<\/li>\n
- \n
Fixed typographic errors (tatal<\/code> rather than total<\/code>).<\/p>\n<\/li>\n- \n
Added parenthesis to function invocations (e.g: getTax()<\/code> rather than getTax<\/code><\/p>\n<\/li>\n- \n
Removed redundant invocations<\/p>\n<\/li>\n
- \n
More<\/p>\n<\/li>\n<\/ol>\n<\/div>\n
