InternalError

非标
This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

InternalError object indicates an error that occurred internally in the JavaScript engine.

Example cases are mostly when something is too large, e.g.:

  • "too many switch cases",
  • "too many parentheses in regular expression",
  • "array initializer too large",
  • "too much recursion".

范例

Too much recursion

This recursive function runs 10 times, as per the exit condition.

function loop(x) {
  if (x >= 10) // "x >= 10" is the exit condition
    return;
  // do stuff
  loop(x + 1); // the recursive call
}
loop(0);
					

Setting this condition to an extremely high value, won't work:

function loop(x) {
  if (x >= 1000000000000)
    return;
  // do stuff
  loop(x + 1);
}
loop(0);
// InternalError: too much recursion
