javascript regular expression to not match a word

Question

How do I use a javascript regular expression to check a string that does not match certain words   For example  I want a function that  when passed a string that contains either abc or def  returns false    abcd  -  false   cdef  -  false   bcd  -  true  EDIT  Preferably  I want a regular expression as simple as something like    abc   but it does not deliver the result expected as I need consecutive letters    eg  I want myregex  if   myregex test  bcd     alert  the string does not contain abc or def      The statement myregex test  bcd   is evaluated to true
