In the initial commit to this project, you have been provided with files that contain a JavaScript module and some associated tests. Currently supporting functions (isSkippedValue, isNumericValue, isNothingValue, and isAcceptableValue) used by our calculator are causing the tests to fail. Your task is to rework these 4 functions so that they work as expected, making the tests pass.
The calculate function runs an arithmetic calculation based upon an array of inputs (eg. [2, '*', 10])
Each input should be either a number or an operand (+, -, *, /)
Our upstream data is inconsistent, so we intentionally accept it and deal with it in the following ways:
- Stringified numbers (eg.
'2') should be treated as numbers NULLshould be treated as zeroundefinedvalues should be ignored- Empty string (eg.
'') values should be ignored
.eslintrc.js - a config file for eslint
hazyCalculator.js - this file contains a JavaScript module for performing calculations with imperfect data
tests.js - this file contains tests for the functions in the hazyCalculator module
package.json - this file sets up the Node project including all the dev dependencies
.gitignore - this file sets the project up to ignore the node_modules folder when committing to git
