Trim is much faster than parse for your example. It is a native function.
speedtest: func [][
st: now/precise
loop 10000 [stripped: trim/with teststring "' "]
et: now/precise
print ["10000 trim/with took:" difference et st]
st: now/precise
strip: charset [#" " #"'"]
not-strip: complement strip
loop 10000 [
stripped: copy ""
parse teststring [any [copy str some not-strip (insert tail stripped
str) | some strip]]
]
et: now/precise
print ["10000 parse took:" difference et st]
]
>> speedtest
10000 trim/with took: 0:00:00.007205
10000 parse took: 0:00:00.05729
