Question

This is my response data:

var data = [{
                'name': 'ragu',
                'taxprice': '20'
            } {
                'name': 'ram',
                'taxprice': '20'
            } {
                'name': 'sandy',
                'taxprice': '20'
            } {
                'name': 'ramu',
                'taxprice': '20'
            }];

Use (Array.reduce)

var data = [{'name': 'ragu', 'taxprice': '20' }, {'name': 'ram', 'taxprice': '20'}, {'name': 'sandy', 'taxprice': '20'}, { 'name': 'ramu', 'taxprice': '20'}];
                
var result = data.reduce((a,c) => a + Number(c.taxprice), 0);
console.log(result);

Many dupes here. – mplungjan May 24 '18 at 07:38
Agreed but with conversion to number may be hard to find. Hence, added the solution. – Nikhil Aggarwal May 24 '18 at 07:41
