Can you give an example?
get: function( num ) {
return num != null ?
// Return just the one element from the set
( num < 0 ? this[ num + this.length ] : this[ num ] ) :
// Return all the elements in a clean array
slice.call( this );
},
That's from jQuery 2.1.3.
And from the same place:
function cache( key, value ) {
// Use (key + " ") to avoid collision with native prototype properties
(see Issue #157)
if ( keys.push( key + " " ) > Expr.cacheLength ) {
// Only keep the most recent entries
delete cache[ keys.shift() ];
}
return (cache[ key + " " ] = value);
}
That's after looking through about 1/10 of the library. I'll bet there
are more. I'll also bet this sort of thing appears in every single
major library out there.
