For better compatibility with existing code, Array.prototype.concat() has
|
|
non-standard behavior by default for trailing non-existent elements of
|
|
the concat result, see
|
|
https://github.com/svaarala/duktape/blob/master/ecmascript-testcases/test-bi-array-proto-concat-nonstd-trailing.js.
|
|
|
|
If this option is given, concat() will behave in a strictly conforming
|
|
fashion, ignoring non-existent trailing elements in the result length.
