    \$\begingroup\$ I'm using google chrome, and these are all giving undefined. \$\endgroup\$ Commented May 14, 2015 at 19:19
  • \$\begingroup\$ It must be very firefox specific then. Sorry for the inconvenience. \$\endgroup\$ Commented May 15, 2015 at 16:44
  • \$\begingroup\$ Why are these all special characters? Why not just use printable ASCII? (easier to type, more reliable, and only 1 byte for golfing) \$\endgroup\$ Commented Feb 10, 2016 at 20:02

    \$\begingroup\$ This doesn't really work for Math because it doesn't have a .prototype attribute. Removing Math, though, I managed to golf this down to a 114-byte snippet that assigns them all to single-byte letters. You can find it Object.getOwnPropertyNames(P=x.__proto__).map((p,i)=>P[String.fromCharCode(i+65+6*(i>25))]=P[p]))" rel="nofollow noreferrer">here. \$\endgroup\$ Commented Dec 3, 2016 at 20:50

    \$\begingroup\$ You can also golf my solution to 106 bytes at the expense of moving all these properties to the range À-ÿ, which is still 1 byte each in the ISO-8859-1 encoding (which JS supports). In Firefox 50, this unfortunately puts the .localeCompare method on ×, but that shouldn't usually be an issue. Object.getOwnPropertyNames(P=x.__proto__).map((p,i)=>P[String.fromCharCode(i+192)]=P[p]))" rel="nofollow noreferrer">source \$\endgroup\$ Commented Dec 3, 2016 at 21:59
