Tests:

Lo
_(AssetCategory).omit([AssetCategory.NONE3]).values().value()
Filter / Map
Object.keys(AssetCategory).filter(x => x !== AssetCategory.NONE3);
Map / Delete
var map = new Map(Object.entries(AssetCategory)); map.delete("NONE3") Array.from(map.keys());
Reduce
Object.keys(AssetCategory) .reduce( (res, x, i) => { if(x !== 'NONE3') { res.push(x); } return res; }, [] );
Slice
Object.keys(AssetCategory).slice(1)
Yielder
function *magic(col, token) { for(var i = 0; i < col.length; i++) { if(col[i] !== token) { yield col[i]; } } } Array.from(magic(Object.keys(AssetCategory), 'NONE3'));
