loop through 'distinct' values and ignore duplicates - javascript -

loop through 'distinct' values and ignore duplicates - javascript -

i'm rewriting question explain better,

i have list of objects shown in image.

these have property statuscode: 62467 journey property goes like: 0,1,2,3,3,4,4,4,4

i want loop through these objects , homecoming first of duplicated objects same journey number.

so want homecoming bold objects: 0,1,2,3,3,4,4,4,4

$.each(points, function (index, point) { (i = 0; < journeynumber.length; i++) { if (point.k.journey === journeynumber[i] && point.k.statuscode === '62467') { console.log(point); latlngs.push(point.j.aa.k); latlngs.push(point.j.aa.b); } } });

the screenshot log of console.log(point), ideally loop within returns first object of same journey number.

hope makes sense , give thanks time.

you can track numbers have been dealt with, and, on finding duplicates of them, skip them.

var already_seen = []; //container logging unique values $.each(points, function(index, point) { if (already_seen.indexof(point) !== -1) return; //if in container, skip already_seen.push(point); //log unseen values in container (i = 0; < journeynumber.length; i++) { if (journey === journeynumber[i] && statuscode === '62467') { latlngs.push(lat); latlngs.push(lng); console.log(journey) } } });

javascript loops for-loop
