Why is this PR for?
Current implementation of
fc.optiondoes not allow the user to produce something else thannull.By using some tricks we can make it produce other values:
fc.option(arb).map(v => v === null ? otherValueForNull : v).This PR updates
fc.optionso that it can receives an extra parameter to specify the null value we want it to produce:fc.option(arb, { nil: undefined }).Incomplete PR, need to update UTests and document the change
In a nutshell
Potential impacts
Nothing.
