What is the best way to merge these functions?

Question

What is the best way to merge these functions?

As I dive into JavaScript functions, I find myself with three almost identical ones:

function filterAll() {
    location.hash = "/"
}

function filterCompleted() {
    location.hash = "/completed"
}

function filterActive() {
    location.hash = "/active"
}

I wonder if there's a way to consolidate these functions into one, where I can specify the desired parameter each time I call it. Here's my attempt at restructuring them:

function filters(filterType) {
    if (filterType === 'all') {
        location.hash = "/";
    } else if (filterType === 'completed') {
        location.hash = "/completed";
    } else if (filterType === 'active') {
        location.hash = "/active";
    }
}

filters('all');

Answer №1

To easily map different actions to URLs, you can utilize an object literal in JavaScript like this:

const actions = {
  all: '/',
  completed: '/completed',
  active: '/active'
}

function filter(action) {
  location.hash = actions[action];
}

// Usage example
filter('all');
filter('completed');
filter('active');

If passing a string is not desired, another approach would be treating the object as an enumeration:

function filter(action) {
  location.hash = action;
}

// Usage example
filter(actions.all);
filter(actions.completed);
filter(actions.active);

While using multiple consts can work as mentioned by others, I prefer to keep things simple and avoid excessive variable declarations.

I'm not entirely certain about your intentions, could you please provide some additional context? If your goal is to pass three variables, then the code snippet you shared appears to be suitable. However, if you are looking to pass a single variable with three data points, I would recommend utilizing an object.

var selections = {first:"/", second: "/completed", third: "active"};

You can access the values by using a method like alert(selections.first);

Here is a possible solution for you to consider:

function filterItems(value) {
    switch (value) {
        case 'all':
            location.hash = "/";
            break;
        case 'completed':
            location.hash = "/completed";
            break;
        case 'active':
            location.hash = "/active";
            break;
        default:

If you want to streamline your code, consider combining the three functions below into a single function that only requires one parameter.

Step One

To start, define three const variables:

const all = '/';
const completed = '/completed';
const active = '/active';

Step Two

Next, create the following function:

function myFilter(filterType) {

  location.hash = filterType;
}

Step Three

Now you can call the function with different values:

myFilter(all);
myFilter(completed);
myFilter(active);

It seems like this is the solution you've been searching for.

function sortOptions(optionType) {
    if (optionType == 'ascending') location.hash = "/asc";
    if (optionType == 'descending') location.hash = "/desc";
}

While I suggest a different approach, here is an example of how to use the function:

sortOptions('ascending'); // Set ascending order
sortOptions('descending'); // Set descending order

Initially, it is important to establish these variables as constants, solely for the purpose of serving as parameters for actions.

The following code snippet can be utilized:

function filters ( action ) {
 return action==="all" ? location.hash = "/" : action==="completed" ? location.hash = "/completed": action==="active" ? location.hash = "/active" : "No Match Found";
}

In order to evaluate the function, a straightforward example has been provided:

let tod = "all"; 
let com = "completed"; 
let act = "active";

//Upon executing this code in your browser, you will have access to all necessary information.

[filters(tod),filters(com),filters(act)].forEach;
