JS warnings at load time

JS warnings at load time

jq v1.10.2
firefox v26.0

When jQuery is loaded when the page opens, several JS warnings occur. The warnings do not affect the operation of JQ but they are a distraction when trying to debug JS scripts.

There are no such warnings for v1.4.2, and only the syntax error warning (sheesh!) for 1.8.3. The trend seems to be: more warnings in later versions.

Is this to be expected? That is, will these warnings continue to happen in future versions?
