Question

What are the most effective strategies for creating a function that sorts and filters arrays based on multiple parameters?

Within our game catalog, we have implemented a series of filters to streamline the process of finding games.

The games are grouped by platforms (HTC, PSVR, PS5, Favorites), and when you click on a specific tab, it triggers a calculated property called showPS5Games. This property takes into account various parameters such as selected genre, sorting preferences, checkboxes for "For children" and "For two," and the ability to search for games by name, tag, or genre. These parameters can be combined in any way to customize the gaming experience.

Here is the full code for showPS5Games:

showPS5Games: state => (
  query,
  genre,
  isChild,
  isLocalMultiplayer,
  selectedSort
) => {
 [Code snippet remains unchanged]

I initially developed a complex function with multiple conditional statements to cover all possible combinations, but this approach lacks optimization and visual appeal. Additionally, I've encountered an issue where filtering the array based on both selected checkboxes does not function correctly - only one checkbox works as intended. What would be the most effective way to refactor this code?

Answer №1

There appears to be a lot of repeated logic in this code snippet. A more efficient approach would involve tidying up the if statements, such as:

if (genre == "все" && isChild && isLocalMultiplayer) {
...
} else if (isChild && isLocalMultiplayer) {

Some of these conditions could potentially be combined within nested if statements:

if (isChild && isLocalMultiplayer) {
    if (genre == "все") {
    ...
    }
}

Furthermore, simplifying the returns for similar reasons would also be beneficial. For instance, the lengthy return statement below:

      return (
    (game.category == "ps5" &&
      isChild &&
      game.isLocalMultiplayer &&
      game.title.toLowerCase().includes(query)) ||
    (game.category == "ps5" &&
      isChild &&
      game.isLocalMultiplayer &&
      game.genre.includes(query)) ||
    (game.category == "ps5" &&
      isChild &&
      game.isLocalMultiplayer &&
      game.tag.includes(query))
  );

Could likely be condensed down to something like this:

 return (
    game.category == "ps5" &&
    isChild &&
    game.isLocalMultiplayer && 
   (game.title.toLowerCase().includes(query) || 
    game.genre.includes(query) ||
    game.tag.includes(query))
);

By making these adjustments, you may have a clearer path forward in resolving any other issues present in your code. Best of luck!
