Defer execution of function and preserve arguments. Aka thunkify
// via https://www.oreilly.com/library/view/you-dont-know/9781491905197/ch04.html
function foo(x, y) {
return x + y
}
function thunkify(fn) {
var args = [].slice.call( arguments, 1 );
return function(cb) {
args.push( cb );
return fn.apply( null, args );
};
}
var fooThunk = thunkify(foo, 3, 4);
// later
fooThunk(function(sum) {
console.log( sum ); // 7
});
