Regex - starts with a particular string but does not end with another substring

Question

Given two strings s1 and s2, I am trying to write a regex that will match a string that starts with s1 but does not end with s2

Answer 1

You can use startsWith and endsWith

let arr = [`TEST-101`, `TEST-SOME-DESC`,`TEST-101-BAD`,`TEST-SOME-DESC-BAD`]

arr.forEach(e=>{
  console.log(e, e.startsWith('TEST') && !e.endsWith('BAD'))
})
