コールスタック・サイズの最大は? どこまで関数は深く呼び出せるのか? (JavaScript)
コールスタック・サイズの最大は?
どこまで関数は深く呼び出せるのか?
例えばこんなコード:
// 深く潜る
function diveDeep(n) {
return diveDeep(n + 1);
}
再帰呼び出しをしているが、終了条件が無いので止まらない。
で、最大でどのくらいまで深く関数を呼べるのか試してみた。
TL;DR 結果は以下の通り
PCの環境の違いとか、ブラウザの実行状況などで、差が出てくるので、
何回か試してみて、一番大きかった数字を書いた。
順位 | ブラウザ | バージョン | 最大コールスタック・サイズ |
---|---|---|---|
1 | Node.js(v8) | v6.9.2-x86 | 31,444 |
2 | Chrome(v8) | 54.0.2807.0 | 31,424 |
3 | Firefox | 50.0 | 15,538 |
4 | Edge | 14.14393 | 11,528 |
5 | IE11 | Trident/7.0 | 10,787 |
6 | jjs(nashorn) | 1.8_60 | 1,187 |
- | Node.js(v8) | v6.9.2-x86 | 31,444 |
- | Node.js(v8) | v6.9.2-x64 | 15,699 |
- | Node.js(v8) | v7.2.1-x86 | 31,412 |
- | Node.js(v8) | v7.2.1-x64 | 15,664 |
- | Chrome Canary | 57.0.2947.0 | 4,638 |
32bit版のv8がダントツ。Google, Mozilla, Microsoftの順って感じ。
64bit版のv8になると半減するね。まぁ、そういうもんか。
Canaryはカナリひどい。

HTMLのソース
いくつかのブラウザで試してみた。Chrome, Firefox, Edge, IE11 など。
<!doctype html>
<meta charset="UTF-8">
<p>Maximum call stack size:</p>
<script src="max-call-stack-size.js"></script>
JavaScriptのソース
ブラウザ以外では、nodeとjjs (nashorn; Javaに付いているやつ) で試してみた。
// 深く潜る
function diveDeep(n) {
try {
return diveDeep(n + 1);
} catch (e) {
return {count: n, error: e};
}
}
// メイン
displayVersion(); // バージョンを表示
var result = diveDeep(0); // 深く潜る
// 結果を表示
pr('Maximum call stack size: ' + result.count);
pr('Error: ' + result.error);
var keys = (Object.getOwnPropertyNames || Object.keys)(result.error);
for (var i in keys)
pr('Error.' + keys[i] + ': ' + result.error[keys[i]]);
// ブラウザのバージョン等を表示
function displayVersion() {
pr(typeof navigator !== 'undefined' &&
navigator.userAgent &&
'Browser: ' + navigator.userAgent ||
typeof process !== 'undefined' &&
process.version &&
'Node.js: ' + process.version ||
'other');
}
// 表示
function pr(x) {
if (typeof document !== 'undefined' && document.writeln)
document.writeln((x + '\n\n').split('\n').join('<br/>\n'));
/*else*/ if (typeof console !== 'undefined' && console.log)
console.log(x);
else if (typeof print !== 'undefined')
print(x);
}
