I have encountered an issue while implementing the Revealing Module Pattern, as I am struggling to expose a modified private property.
var myRevealingModule = (function(){
var name = 'Samantha';
function updateName () {
name = name + ' Smith';
}
return {
fullName: name,
set: updateName
};
}());
// Example usage:
myRevealingModule.set();
console.log(myRevealingModule.fullName); // Output is "Samantha" instead of the expected "Samantha Smith".
const userDetails = {
completeName: userName,
update: setUsername
};
This code snippet utilizes the values stored in the variables userName and setUsername. It does not establish a direct link to the original variable, essentially creating a copy of userName.
In order to maintain a reference to a variable using closures, it is essential to implement a corresponding fetchName method.
var secretModule = (function(){
var username = 'Alice';
function addSurname () {
username = username + ' Smith';
};
function getFullName () {
return username;
};
return {
fullName: username,
set: addSurname,
get: getFullName
};
}());
When a value is an attribute within an object or array, exporting the entire object or array will allow external users to see any updated changes as it is done by reference. However, this method can be somewhat risky due to the complexity of handling variable exports with scalar/object copy and reference dichotomy.
