There is no reason to set the prototype of F in a closer inside each
iteration of the loop. You can set that up before using it in the loop
like this:
function F()
{
this.a = 'a';
}
F.prototype = {
getA : function ()
{
return this.a;
},
setA : function (b)
{
this.a = b;
}
};
var x = [],
i = 0;
for (i = 0; i < 10; i +=1) {
x.push(new F());
x[i].setA("Name " + i);
}
for (i = 0; i < 10; i +=1) {
console.log(x[i].getA());
}
// Prints out Name 0, Name 1,... Name 9
