Why create a closure when you can just create a plain old function? It looks as simple as it is. No need to complicate things by calling the new function either.

Bezier.prototype.getLength = function() {
var length = … // expensive computation
this.getLength = new Function (“return ” + length);
return length;
}

[...] Memoization is a functional programming technique used to cache the result of expensive method calls for later re-use; this allows us to avoid repeatedly performing an expensive calculation when the result has already been calculated once. Today I stumbled accross an interesting method of achieving memoization in Javascript for nullary functions (i.e. functions taking no arguments); I was curious to see if the same could be achieved with Ruby.

Great article!

Could you please correct shortened memoizeConstantMethod to define local ‘value’ variable

The current version does not work correctly when called more then once for different methods.

Very cool technique, I wrote something like this in java some time ago, never thought about a javascript implementation. Great content you have on your blog! Thanks

This strikes me as something I might actually use in a number of practical cases though. Thanks for going into such detail, great explanations.
