I tend to avoid parseInt unless I explicitly need a specific radix. I find the Number function much more reliable in parsing numbers. ['1', '7', '11'].map(Number) And if I explicitly need integers I can always filter the result ['1', '7', '11'].map(Number).filter(Number.isInteger) It also doesn't silently parse '123thisisnotanumber' or `0x11`
