* CODERBYTE BEGINNER CHALLENGE *

* *

* AB Check *

* Using the JavaScript language, have the function ABCheck(str) take the str *

* parameter being passed and return the string true if the characters a and b are *

* separated by exactly 3 places anywhere in the string at least once *

* (ie. "lane borrowed" would result in true because there is exactly three characters *

* between a and b). Otherwise return the string false. *

* *

* SOLUTION *

* I am goint to use a RegExp to see if the patter [a...b] exists anywhere in the *

* string. If it does then return true else return false. *

* *

* Steps for solution *

* 1) Use RegExp pattern to search string for pattern a...b *

* 2) If found return true *

* 3) Else return false *

* *
