(Sorry, this is slightly OT.)
var the_array = ["foo", "bar", "baz", "qux"];
//Is there a simpler way to do the following than what’s here?
var the_lookup = {};
the_array.forEach( function(i) { the_lookup.i = true } );
========
In Perl this is easy:
my @array = qw(foo bar baz qux);
my %lookup = map { $_ => 1 } @array;
Anything of the sort coming in JS, does anyone know? Maybe in some of
the newer ES5 goodies?
