Arranging the list based on priority

Question

Arranging the list based on priority

I have an array called criticalityTypes that contains three different levels of criticality: 'CRITICALITY_LOW', 'CRITICALITY_HIGH', and 'CRITICALITY_MEDIUM'.

Currently, the order of these criticality types is random, which means sometimes 'CRITICALITY_LOW' is in position 1, and other times it's at position 2 or 'CRITICALITY_MEDIUM' at position 0.

What I want to achieve is to sort these criticality types in a specific order regardless of how they are randomly arranged. The desired order is: ['CRITICALITY_HIGH', 'CRITICALITY_MEDIUM', 'CRITICALITY_LOW'].

I've attempted to use a sorting function like this:

return criticalityTypes.sort((a, b) => {
    if (a < b) return -1;
    if (a > b) return 1;
});

However, my current approach has not been successful. Can anyone provide assistance on how I can achieve the desired ordering?

If you have a list of objects and want to sort them based on a specific order, one way to do it is by sorting the objects according to the values difference.

var priorityLevels = ['LOW', 'HIGH', 'MEDIUM'],
    order = { HIGH: 1, MEDIUM: 2, LOW: 3 };

priorityLevels.sort((a, b) => order[a] - order[b]);

console.log(priorityLevels);

Here's an alternative approach:

const priorityLevels = ['LOW_PRIORITY', 'HIGH_PRIORITY', 'MEDIUM_PRIORITY'];
let sortedTasks = [];
let targetOrder = ['HIGH_PRIORITY', 'MEDIUM_PRIORITY', 'LOW_PRIORITY'];

 for (var j = 0; j < targetOrder.length; j++) {
    if (priorityLevels.indexOf(targetOrder[j]) > -1) {
        sortedTasks.push(targetOrder[j]);
    }
 }

 console.log(sortedTasks);

    }
 }

 console.log(sortedTasks);

The issue at hand stems from the lack of clear definition for what constitutes an "order" in relation to the items provided by the API. These items are more conceptual in nature rather than being quantifiable, making it difficult to assign a numerical value as an order. The string representation serves primarily for display purposes.

While you may not have the ability to modify the API itself, if there are only three possible items and they always need to be displayed in a specific sequence, one approach could be to create a placeholder function that mimics the current sorting behavior. This placeholder can serve as a temporary solution until a more concrete method of determining the ordering numerically is available; after all, ascending or descending orders rely on quantifiable values to make sense.

function criticalityTypes(a,b){
    return ['CRITICALITY_HIGH', 'CRITICALITY_MEDIUM', 'CRITICALITY_LOW'];
}
