Flatten Array in CFML
Take a nested list and return a single list with all values except nil/null
exercism fetch cfml flatten-array
Take a nested list and return a single flattened list with all values except nil/null.
The challenge is to write a function that accepts an arbitrarily-deep nested list-like structure and returns a flattened structure without any nil/null values.
To run the code in this exercise, you will only need to have CommandBox CLI installed. This binary runs CFML code from the command line.
To run the tests,
cd into the exercise folder and run the following:
box task run TestRunner # Or start up a test watcher that will rerun when files change box task run TestRunner --:watcher
The tests leverage a library called TestBox which supports xUnit and BDD style of testing. All test suites will be written in the BDD style which uses closures to define test specs. You won't need to worry about installing TestBox. The CLI test runner will take care of that for you. You just need to be connected to the internet the first time you run it.
