Using Named Function Expressions Properties In JavaScript

I created a memoize function in one of my previous posts. It used a memoized fibonacci function like so:

var fib = memoize(function(n) { if (n < 2) { return n; } return fib(n - 1) + fib(n - 2); });

And memoize looked like this:

var memoize = function(callback) { var results = {}; return function(n) { if (results[n] !== undefined){ return results[n] } results[n] = callback(n); return results[n]; }; };

If the memoize function expression was given a name and then directly assigned to the above, memoize could be simplified. Additionally, since 0 is not passed through memoize, the undefined check can be generalized to a falsy check. Meaning that the undefined cache check can be avoided too:

var memoize = function(callback) { return function compute(n) { return compute[n] || (compute[n] = callback(n)); }; };

JavaScript Munchkins: Function Expressions

This series of posts teaches JS using the game Munchkin. A fun way to learn how to play is by watching the Table Top Video staring Felicia Day, Steve Jackson and Sandeep Parikh. Declared functions, like the Plutonium Dragon from the last post, are built in memory right as we load the program. Function expresessions are assigned to a varaible so they'll only be loaded when its reached inside the program. // Syntax of a Function Expression var variable = function functionNameIsOptional (parameters) { code to be executed }; The function name above is optional. If the function has no name, then its an anonymous function. // example of calling a Function Expression variable(parameters); You'll notice above that the variable name includes parentheses, and we've included parameters to be used by the function it contains. Lets see an example

Call the Function Expression combatStrength(playerLevel, powerUps);
