  • lodash union

     
    var a = [ 'a', 'b', 'c' ];
    var b = [ 'b', 'd', 'a', 'e', 'f' ];
    var c = _.union(a, b);

  • new Set

     
    var a = [ 'a', 'b', 'c' ];
    var b = [ 'b', 'd', 'a', 'e', 'f' ];
    var c = [...new Set([...a ,...b])];

  • lodash uniq spread

     
    var a = [ 'a', 'b', 'c' ];
    var b = [ 'b', 'd', 'a', 'e', 'f' ];
    var c = _.uniq([...a, ...b]);
