how to Pass a JavaScript function name as parameter and replace function name like parameter-CodePudding

Its just an experiment

I can pass function name ass parameter but it's called the same name function.

function refreshContactList(id) {
    console.log(`Hello World ${id}`);
}

function addContact(id, refreshCallback) {
    refreshCallback(id);
}

addContact(1, refreshContactList);

like that.

but I want to change the function name, so its changes the name of the function like that ( image )

function addContact(id, refreshCallback) {
    
    function refreshCallback(id) {
        console.log(`Hello World ${id}`);
    }
    
}

addContact(1, refreshContactList);

is there any way to achieve that?

CodePudding user response：

In your picture, you pass not name of function but the reference to this function. If you really want to call the top-level function by the given name (that is, by the string with the name of this function), you can use a cross-platform method that works equally well in node.js, browsers (traditionally, except for Internet Explorer) and other platforms: globalThis:

function a() {
  console.log('a')
}

function b() {
  console.log('b')
}

function callByName(name) {
  globalThis[name]
}

callByName(a)

Is Nested Functions you want?

function addContact(id) {
    function anotherThing() {
        console.log(`Hello World ${id}`);
    }
    
    return { anotherThing };

}

addContact(1).anotherThing();
