Major update breaking changes: - ESLint 7.0.0 (https://eslint.org/docs/user-guide/migrating-to-7.0.0) now includes .eslint.rc.js in its list, which is fine for us. Other changes are not applicable for us. - eslint-plugin-mocha (https://github.com/lo1tuma/eslint-plugin-mocha/blob/master/CHANGELOG.md#700-may-13-2020) drops support for ESLint <7, but this CL updates to 7+. Other changes are not applicable for us.

/**
|
|
* `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.

* @sig (...x -> a) -> ((e, ...x) -> a) -> (...x -> a)
|
|
* @param {Function} tryer The function that may throw.
|
|
* @param {Function} catcher The function that will be evaluated if `tryer` throws.
|
|
* @return {Function} A new function that will catch exceptions and send then to the catcher.
|
|
* @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') // => []
|
|
* R.tryCatch(() => { throw 'this is not a valid value'}, (err, value)=>({error : err, value }))('bar') // => {'error': 'this is not a valid value', 'value': 'bar'}
