I believe you mistyped that.  Did you not mean "[tr;dl]"?

For it did seem that my argument was Too Reasonable, and you Didn't 
Listen.

The amusing thing is that I agree with your advice entirely.  The OP 
_should_ learn to use the newer Array.prototype methods.  They would 
improve the posted code sample significantly.  But your suggestion 
that this had to do with efficiency was bogus.  Rarely will a 
well-written block that uses `Array. prototype.some` be more efficient 
than its (appropriately-written) counterpart written with a 
`for`-loop.  But except in the most performance-critical sections of 
code, I would recommend the former, since clean, readable code is more 
maintainable, and such performance differences rarely impose a 
substantial penalty.
