如何从nodejs中的给定字符串中提取特定字符串

Question

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.

Answer 1

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) })
