Sort array of object based on another string array

Question

I have 2 arrays

a = [ { label:"Price", value:10 }, { label:"Active", value:false }, { label:"Category", value:"food" }, { label:"Remarks", value:"none" } ]; b = ["Active","Category","Price"]; 

How do I sort a according to the order of b? Can I use ramda?

Something succinct like the following would be ideal

R.sortBy(R.pipe(R.prop('label'), R.indexOf(R.__, a)))(b); 

Similar to this issue, except I don't have index, so I cannot use indexOf method.
Sort an array of objects based on another array of ids

Appreciate your help!

There might be a more succinct option but here is how I'd do it.

const list = [ {label:"Price", value:10}, {label:"Active", value:false}, {label:"Category", value:"food"}, {label:"Remarks", value:"none"} ]; const labels = ["Active","Category","Price"]; const sorted = list.sort((a, b) => { const aIndex = labels.indexOf(a.label); const bIndex = labels.indexOf(b.label); return aIndex - bIndex; }); console.log(sorted);
