try-this v1.1.0

try this

Function for avoiding try catch boilerplate.

Why?

Often we want to just try some function that could throw and do not trigger any error warning, but just provide a fallback value to use instead or reacting in the same closure. In JS there's lot of pain into doing this as we would need to create two closures, a let variable, re-write it for each use case. For example this is very common:

let value

try {
  value = trySomeThrowingFunction()
} catch () {
  value = fallback
}

return value

With this package we got one liner function:

const { ok, value, error } = tryThis(throwingFunction)

Options

We can provide an options object which will get a fallback value (of the same type as the expected value) and / or an 'else' function which can return the same kind of type as the original function or be void and the original error (or fallback) will be passed back.

const { ok, value, error } = tryThis(throwingFunction, {
  fallback: 'some value',
  else: () => 'some equivalent function'
})

The else function will be evaluated the same way as the original function. The fallback value is the last resort value.
