nodejs out of memory

Question

I came across a curious issue today. This may be an easy answer for others, but it has me stumped. Why does the code below cause a memory error?

var cur =          


        

Answer 1

I don't get a memory allocation error when I run your script. How much RAM is on your system?

Edit Ok with the author's updated notes, I can replicate it.

Node is trying to convert your entire array to a string. The array is 16777216 elements long. Each element contains a number at least 9 digits long. Converting that to a string 150,994,994 characters long. Its just a huge operation that is exceeding the memory capabilities of node.
