Filter multidimensional array based on another array
Solution 1:
Use Array.prototype.filter():
var myList = [{"Fund":"Edelweiss1","Rank":10},{"Fund":"Edelweiss","Rank":5}, {"Fund":"Edelweiss3","Rank":3}];
var rngarray = [6,10];
var filtered = myList.filter(item => item.Rank >= rngarray[0] && item.Rank <= rngarray[1]);
console.log(filtered);
