There is no way to distinguish in "STRINGTo" where the To begins. Technically putting STRING all in caps makes it non CamelCase — Jorge.V, Jun 21 '18 at 07:12

Please use this regular expression.

yourString.replace(/([A-Z]+)/g, " $1").replace(/([A-Z][a-z])/g, " $1")

or

yourString.replace(/([A-Z]+)/g, " $1")

The second `replace` adds a couple extra spaces between the first few words. – thgaskell Jun 21 '18 at 07:22
