Remove Empty Elements From An Array In Javascript Typedarray Org One effective strategy is to employ the .filter() method prior to mapping. this way, you first filter out unwanted items and then map the remaining elements: return img.src.split('.').pop() !== "json"; keep non json files. }).map(function(img) { return img.src; map to src value. });. Use the array.filter() method to exclude the elements you want to skip over. use the array.map() to map over the remaining array elements. .filter(employee => { if (employee.id === 2) { return false; } return true; }) .map(employee => { return employee.name; }); console.log(names);.
