Why jquery defined two methods for the same purpose? size and length -

after reading this se discussion question pops up. why jquery defined 2 methods same purpose? there purpose missed?

don't know belongs wiki discussion. if please guide me change so.

i guess didn't think through, unless perhaps earliest versions had reason. find source 1.2.6, , unchanged current version.

edit: it seems have been unchanged since version 1.0.1.

the documentation .size() suggests should not used.

you should use .length property instead, faster.
