Jannik und Felix sind da. Wir reden über RAM und vRAM (Video-RAM).
Robert baut ein Summierskript, basierend auf dem Memoizer von Crockford:
<input type="text" id="input">
</input>
<button id="go">go</button>
<div id="output">
</div>
<script>
var memoizer = function (memo, formula) {
var recur = function (n) {
var result = {
calc:"",
notation:""
}
result.calc = memo.calc[n];
result.notation = memo.notation[n];
if (typeof result.calc !== 'number') {
result = formula(recur, n);
//~ console.log(result);
memo.calc[n] = result.calc;
memo.notation[n] = result.notation;
}
return result;
};
return recur;
};
var sumUp = memoizer({calc:[0, 1], notation:["", "1"]}, function (recur, n) {
var result = {
calc:"",
notation:""
}
result.calc = parseInt(n,10) + recur(n -1).calc;
result.notation = n + "+" + recur(n -1).notation;
return result;
})
var input = document.getElementById("input");
var button = document.getElementById("go");
var output = document.getElementById("output");
button.onclick = function() {
// alert(input.value);
res = sumUp(input.value);
console.log(typeof (input.value | 0));
console.log(res);
output.innerHTML = res.calc + " = " + res.notation;
}
</script>
