$ npm install mimicking-func

const mimickingFunc = require('mimicking-func');

const say = ()=> {};
say.hello = 'hello';
say.hi = 'hi';

function wrapperFunction() {
	return say() {};
}

console.log(wrapperFunction.name);
//=> 'wrapper'

mimicFn(wrapperFunction, say);

console.log(wrapperFunction.name);
//=> 'foo'

console.log(wrapperFunction.say);
//=> '
