I have an array which holds a list of array and the value is in ‘dollars’.
I need to take the max price and min price from that list.

This is what have tried,

var _array = [$1.09,$3.07,$2.223];
var number = Number(_array.replace(/[^0-9.]+/g,""));
a= Math.max.apply(Math,number); // $3
b= Math.min.apply(Math,number); // $1

But its not working, can anyone please help me out.

It could be simple if you correct the error in your list array sort is your friend

var _array = ["$1.09", "$3.07", "$2.223"];
_array.sort(function(a, b) {
    return Number(a.replace(/[^0-9.]+/g, "")) - Number(b.replace(/[^0-9.]+/g, ""));
});

console.log(_array[0], "   ", _array[_array.length - 1]);

Open your browser inspector and run the above code.

Problem is you are having illegal characters in your array. Have them like strings by wrapping in ''.

Do it like bellow

var _array = ['$1.09','$3.07','$2.223'];
var numbers = _array.map(function(curr){
    return Number(curr.replace(/[^0-9.]+/g,""))
})
a= Math.max.apply(Math,numbers); // 3
b= Math.min.apply(Math,numbers); // 1
console.log(a,b)

DEMO

NOTE:- The .map function won’t work on IE8 so you can use for loop there. Like bellow

var _array = ['$1.09','$3.07','$2.223'];
var numbers = [];

for(var i=0;i<_array.length;i++){
    numbers.push(_array[i].replace(/[^0-9.]+/g,""));
}

a= Math.max.apply(Math,numbers); // 3
b= Math.min.apply(Math,numbers); // 1
console.log(a,b)
