Answer 1

More simple and concise solution:

let newArray = array.filter(Boolean);

just pass javascript Boolean (builtin) function inside filter as callback function.

Answer 2

arr = [ { "stockId":2,"vendorId":1,"vendorCode":"Aya - 01","price":2100 }, null, null ]
arr = arr.filter(elem => elem != null)

Answer 3

For example, if you want to remove null or undefined values:

var array = [ { "stockId":2,"vendorId":1,"vendorCode":"Aya - 01","price":2100 }, null, null ];
var filtered = array.filter(function (el) {
 return el != null;
});
 
console.log(filtered);

Answer 4

If you want to remove false values, do something like this

var array = [
 { stockId: 2, vendo`enter code here`rId: 1, vendorCode: 'Aya - 01', price: 2100 },
 null,
 null,
];
newArray = array.filter(item => !!item);
