See this regex:
/^(?=.*Tim)(?=.*stupid).+/
Regex explanation:
^Asserts position at start of string.(?=.*Tim)Asserts that “Tim” is present in the string.(?=.*stupid)Asserts that “stupid” is present in the string..+Now that our phrases are present, this string is valid. Go ahead and use.+or –.++to match the entire string.
To use lookaheads more exclusively, you can add another (?=.*<to_assert>) group. The entire regex can be simplified as /^(?=.*Tim).*stupid/.
