What this snippet does
When memory runs out the kernel kills a process; the service just disappears with no error of its own.
Expected output
Out of memory: Killed process 2841 (node) total-vm:4210112kB
Why practise typing this
Typing monitoring & performance code builds muscle memory for the symbols and indentation Linux uses most, which prose-based typing tests never cover. DevType measures your words per minute and accuracy on this snippet and tracks the individual characters you mistype, so later lessons can target them.
