Second expression in the for loop and ||, both behave as conditionals, i.e. are equivalent to an if statement and the generated instruction will be a branch.

At least it would in C. Of course I'm ignoring the fact that JS is interpreted as will cause a lot of additional bloat, but were not counting that.

No doubt about it. The question was about avoiding the if/else within the for loop body.

In js the for could be replaced with an array of 100 elems and a forEach:

Array.apply(null, { length: 100 }).forEach(function (_, i) { })
