Javascript - Sort Array of objects by 2 Properties

Question

I want to sort an array of objects by 2 different properties.

These are my objects

array = [{ resVal: "25FA15", resFlow: 49, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 1.5 },
 { resVal: "25FA2", resFlow: 52, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 2 },
{ resVal: "45FA2", resFlow: 53, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 },
{ resVal: "35FA2", resFlow: 59, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 }]

I want to sort the array by the higher "resFlow" value, but with the lowest "resHP" value.

I want to put my array like this:

array = [{ resVal: "25FA15", resFlow: 49, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 1.5 },
{ resVal: "35FA2", resFlow: 59, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 },
{ resVal: "45FA2", resFlow: 53, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 },
 { resVal: "25FA2", resFlow: 52, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 2 }]

Hope someone can help me.

Thank you.

You could use a chained approach for a specified order of keys and their sort order.

The array is sorted by the properties

• resHP, ascending and
• resFlow, descending.

It works with calculating the delta and this reflects the relation of the two objects. If the value is zero, then the two values are equal and the next delta is calculated and returned.

var array = [{ resVal: "25FA15", resFlow: 49, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 1.5 }, { resVal: "25FA2", resFlow: 52, resName: "Rendimiento Tri-Seal Completo", resPhoto: "Tri-Sealseries.png", resHP: 2 }, { resVal: "45FA2", resFlow: 53, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 }, { resVal: "35FA2", resFlow: 59, resName: "Rendimiento Hi-Cap Completo", resPhoto: "HighCapseries.png", resHP: 2 }];

array.sort(function (a, b) {
    return a.resHP - b.resHP || b.resFlow - a.resFlow;
});

console.log(array);

.as-console-wrapper { max-height: 100% !important; top: 0; }
