javascript - underscore's some and every functions - susceptible to not short-circuiting? -

are underscore's some , every functions susceptible not short-circuiting?

from reading source, looks can happen if javascript environment not define native some function define native foreach method. can happen though? guess it's plausible plenty ever happen in practice?

technical nitty gritty backing thoughts above:

_.some internally uses _.foreach if native some not defined _.foreach short-circuits when called other underscore functions. respects special breaker homecoming value. this breaker object internal underscore , cannot used non-underscore functions.

i inquire because people have requested breaker made available outside underscore others can break behavior foreach. that's been denied because native foreach implementations (which underscore delegates if available) not respect convention , they're striving consistent behavior. seems _.some , _.every has same inconsistency issue, right?
