Performance bottleneck

[YeskaNova]

Hi,

Thank you for the awesome infinit-tree library. When I try to load 80k+ nodes under a single node, this line incredibly slows down the loading :

flattree/src/flatten.js

Line 123 in 6b0f516

if (node.isLastChild()) {

I think you can change this line with a less expensive check :
if(index === current.children.length-1)

I gained 1.4 seconds with this. Can you confirm that I didn't break something ? It seems to me that the original check does a long roundtrip to just do that simple check.

Thank you,

Yassine

That's a good point. This change will definitely reduce the time for searching the array for the specified node. Thank you for the finding.

Thank you.

Just published 0.11.1 to address the performance issue.
