Remove Duplicates Of Array From Another Array, Javascript

How can i remove duplicated arrays in this data structure? [![enter image description here][1]][1] I got this: ['5', '26', 300], ['7', '10', 20], ['3', '4', 30], ['

Solution 1:

You could filter them:

var a = [[1, 2, 3], [1, 2, 3], [4, 5, 6], [4, 5, 6], ['foo']];
var tmp = [];

var b = a.filter(function (v) {
    if (tmp.indexOf(v.toString()) < 0) {
        tmp.push(v.toString());
        return v;
    }
});

console.log(b);

Solution 2:

In this other reply it was resolved stringifying the arrays, and removing duplicates with a Set. It should be much simpler

Array.from(newSet(jsonData.map(JSON.stringify)), JSON.parse)
