Ho do i call a function injecting into its scope arbitrary variables / functions? I want to define an "update" function that can freely call a series of functions, but they have to be defined and bond in another scope.
I tried with with
but it doesn't work.
Also, I know there are a tons of solutions like passing the object whose functions to call or define a list of arguments and bind them, but since "update" has to be defined by the user, its signature must be just a simple function with no arguments (just like in the code below) but it has to have access to a long list of functions with an arbitrary binding.
function obj (size) {
this.printSize = function () {
console.log(size);
}
}
const obj1 = new obj(1);
const obj2 = new obj(2);
function update () {
printSize();
}
with(obj1) {
update();
}
with(obj2) {
update();
}
