Maximum object children on node js [duplicate]

问题

This question already has answers here:

Are there limits to the number of properties in a JavaScript object? (6 answers)

Closed 8 days ago.

I'm aware that the ECMA script spec says that an object can have infinite children however I also understand many ECMA script implementations do not conform to this. I was wondering if node has a limit on the amount of children an object can have?

Thanks, Ed.

回答1:

Yes it can but until heap out of memory.

var a = {};
var i = 0;
while(true){
    a[i] = null;
    i++;
}

FATAL ERROR: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

So it depends on your memory size.
