Check if the value is a function, using the typeof operator.
typeof
Why needed? Because lodash _.isFunction(value) fails for async generator functions:
_.isFunction(value)
console.log(.isFunction(a_GeneratorFunction_async_named)) console.log(.isFunction(a_GeneratorFunction_async_anonymous))
both print false
false
The z.isFunction returns true for both.
z.isFunction
true
