From http://docs.jsonata.org/string-functions.html: $substringBefore(str, chars) Returns the substring before the first occurrence of the character sequence chars in str. If str is not specified (i.e. this function is invoked with only one argument), then the context value is used as the value of str. If str does not contain chars, then it returns str. An error is thrown if str and chars are not strings. Examples $substringBefore("Hello World", " ")=="Hello"- See Also:
