JavaScript property counterparts

Recently, I've been working on creating alias's for a specific property in my code.

var default_commands = {}
default_commands['foo'] = "bar";

My goal is to create multiple aliases for the key 'foo' in the object.

For example:

default_commands['fu'] = default_commands['foo'];
default_commands['fuu'] = default_commands['foo'];

I want to find a way to simplify this process without having to manually write out each alias.

I attempted:

default_commands['fu','fuu'] = default_commands['foo'];

However, that method did not yield the desired results.

Answer 1

Answer №1

["fu", "fuu"].forEach(function (alias) {
    alternative_commands[alias] = alternative_commands.foo;
});

This situation is not necessarily about creating an interchangeable "alias" as commonly understood:

alternative_commands.fu = 5;
console.log(alternative_commands.foo); // remains "bar", not 5.

Your question left some room for interpretation.

Answer 2

["fu", "fuu"].forEach(function (alias) {
    alternative_commands[alias] = alternative_commands.foo;
});

This situation is not necessarily about creating an interchangeable "alias" as commonly understood:

alternative_commands.fu = 5;
console.log(alternative_commands.foo); // remains "bar", not 5.

Answer №3

This approach offers a solution that can be considered highly adaptable:

function unalias (str) {
  // Implement any preferred method to unalias the string.
  // Here's one potential option:
  var aliases = { "fu": "foo", "fuu": "foo" };
  return aliases[str] !== undefined ? aliases[str] : str;
}

default_commands[unalias("fu")] = 7;
default_commands[unalias("fuu")] = default_commands[unalias("foo")] + 3;
alert(default_commands.foo);

What sets this apart as more versatile? The handling of both read and write operations will flow effectively.

Answer №4

One way to utilize aliases in javascript is by utilizing objects.

In JavaScript, objects are accessed like pointers:

For instance:

var myObject = {greeting: "hello"};
var myAlias = myObject;

myObject.greeting = "goodbye";

console.log(myObject.greeting); => // "goodbye"
console.log(myAlias.greeting); => // "goodbye"

You cannot create an alias for a string, number, boolean, etc.

For example:

var myNumber = 1;
var myAlias = myNumber;

myNumber = 2;

console.log(myNumber); => // 2
console.log(myAlias); => // 1

Note: All types (like Array or RegExp) apart from Int, String, Boolean, null and undefined are treated as Objects.

Stop overanalyzing the situation.

let apple="apple",ap=apple,app=apple,default_functions = {};

default_functions[apple] = "banana";  console.log(default_functions[apple]);
default_functions[ap]  = "cherry";  console.log(default_functions[apple]);
default_functions[app] = "date"; console.log(default_functions[apple]);
