* Remove needless RegExp flag In fixed case, `/g` flag is needless in the boolean context. * Remove needless RegExp capturing Use non-capturing grouping or remove capturing completely when: * capturing is useless per se, e.g. in test() check; * captured groups are not used afterward at all; * some of the later captured groups are not used afterward. * Use test, not match/exec in boolean context match() and exec() return a complicated object, unneeded in a boolean context. * Do not needlessly repeat RegExp creation This commit takes RegExp creation out of cycles and other repetitions. As long as the RegExp does not use /g flag and match indices, we are safe here. In tests, this fix hardly gives a significant performance gain, but it increases clarity and maintainability, reassuring some RegExps to be identical. RegExp in functions are not taken out of their functions: while these functions are called many times and their RegExps are recreated with each call, the performance gain in test cases does not seem to be worth decreasing function self-dependency.
