How does node js handle big data?

CAN node js handle big data?

As it turns out, although Node. js is streaming the file input and output, in between it is still attempting to hold the entire file contents in memory, which it can’t do with a file that size. Node can hold up to 1.5GB in memory at one time, but no more.
