Benchmark: unique coordinates

Script Preparation code:

var coordinates = [];

for (var i=0; i< 5000; i++) {
	coordinates.push(Math.round((Math.random()*360-180)*1e7)/1e7, Math.round((Math.random()*360-180)*1e7)/1e7)
}

Tests:

Array from - Set
var unique = Array.from(new Set(coordinates.reduce((r, a, i) => (i % 2 ? r[r.length - 1].push(a) : r.push([a]), r), []).map(a => a.join('|'))), s => s.split('|').map(Number));
For loops
var temp = []; var unique = []; var uniqueCoords = []; for (var i = 0; i < coordinates.length; i += 2) { temp.push(coordinates[i] + '|' + coordinates[i + 1]); // create some strings } for (var i = 0; i < temp.length; i++) { if (unique.indexOf(temp[i]) === -1) { unique.push(temp[i]); uniqueCoords.push(temp[i].split('|')) } }
