filtering 2d arrays using javascript

Question

I have a 2D array where I need to filter the rows having date field (3d column)

var data = [
[\'1\',\'a\',\'12-12-2019\',\'A\'],
[\'2\',\'b\',\'\',\'A\'],
[\'3\'         


        

Answer 1

It seems pretty straightforward to just use Array.filter, checking to see if the date field is empty or not.

var data = [
['1','a','12-12-2019','A'],
['2','b','','A'],
['3','c','12-1-2019','A'],
['4','d','','A'],
];

var filtered = data.filter(e => e[2]);

console.log(filtered);
