How to extract a particular string from the given string in nodejs

I have strings - 

[ '/home/user/Music/test/project/iit/feature/ABC/release1/PC/en_smoke/smoke_01-login.feature' ]
[ '/home/user/Music/test/project/iit/feature/ABC/release1/PC/en_smoke/smoke_02-logout.feature' ]
[ '/home/user/Music/test/project/iit/feature/ABC/release1/PC/en_smoke/smoke_03-createaccount.feature' ]

I need to extract the string the string "smoke_xx"so whatever the number comes along with smoke_, I need to extract it. I tried many options but didnt worked out. I am new to nodejs. Please help.

with regex of @Lawrence Cherone and use of String.prototype.match

[
  '/home/user/Music/test/project/iit/feature/ABC/release1/PC/en_smoke/smoke_01-login.feature',
  '/home/user/Music/test/project/iit/feature/ABC/release1/PC/en_smoke/smoke_02-logout.feature',
  '/home/user/Music/test/project/iit/feature/ABC/release1/PC/en_smoke/smoke_03-createaccount.feature'
].forEach(path => {
  const smoke = path.match(/smoke_\d+/)[0]
  console.log('smoke :', smoke)
})
