With a Reg. Exp. in JS, Check for 2 Strings Within A String

Question

I'm rubbish at regular expressions, so would someone be able to help me find:

In a string at least one occurrence of of two other strings.

For example looking for the strings foo and bar:

foo foo bar: true

bar: false

foo bar: true

foo barfoo: true

foobar bar: true

foo ba: false

foo foo bar bar: true

Thank you all in advance!

/^(?=.*foo)(?=.*bar).*$/.test("foo bar");

and if you want to match whole words and not fragments :

/^(?=.*\bfoo\b)(?=.*\bbar\b).*$/.test("foo bar");
