How to get the second to last URL string segment with JavaScript?
To get the second to last URL string segment with JavaScript, we can use the string’s split and array’s slice methods.
For instance, we write:
const url = 'http://www.example.com/website/projects/2'
const [secondLast] = url.split('/').slice(-2)
console.log(secondLast)
to split the url by the slashes with split.
Then we call slice to return an array with the last 2 entries of the URL segment string array.
Finally, we destructure the first entry from the returned array and assigned it to secondLast.
Therefore, secondLast is 'projects'.
Conclusion
To get the second to last URL string segment with JavaScript, we can use the string’s split and array’s slice methods.
