tryCatch (

tryer:Function,

catcher:Function

) : Function

tryCatch takes two functions, a tryer and a catcher. The returned function evaluates the tryer; if it does not throw, it simply returns the result. If the tryer does throw, the returned function evaluates the catcher function and returns its result. Note that for effective composition with this function, both the tryer and catcher functions must return the same type of results.

Example

R.tryCatch(R.prop('x'), R.F)({x: true}); //=> true
     R.tryCatch(() => { throw 'foo'}, R.always('catched'))('bar') // => 'catched'
     R.tryCatch(R.times(R.identity), R.always([]))('s') // => []
``

Arguments

tryer: Function

The function that may throw.

catcher: Function

The function that will be evaluated if tryer throws.

Returns

Function

A new function that will catch exceptions and send then to the catcher.
