Intermediate Algorithm Scripting - Search and Replace

JavaScript
1

wrote this code for my algo but didn’t work I tested it using console.log() and it worked
Describe your issue in detail here.

Your code so far

function myReplace(str, before, after) {
      let arr = str.split(/\s/)
let position = arr.indexOf(before)
    let newArr = [...arr]
    newArr[position] = after
    let test= newArr.join(" ")
    return test
}

myReplace("A quick brown fox jumped over the lazy dog", "jumped", "leaped");

Which test cases are failing? I suspect you have case issues.

as Jeremy mentioned, you have case issues.
So for eg:
when given this input:

myReplace("He is Sleeping on the couch", "Sleeping", "sitting")

should return the string

He is Sitting on the couch

But you are returning:
He is sitting on the couch

And the difference is that you didn’t keep the case of the word being replaced.

*this is the correct answer *

function myReplace(str, before, after) {
    let arr = str.split(/\s/)

    console.log(arr.indexOf(before))
let position = arr.indexOf(before)
if (/^[A-Z]/.test(before)) {
    after = after[0].toUpperCase() + after.substring(1)
  } else {
    after = after[0].toLowerCase() + after.substring(1)
  }
    let newArr = [...arr]
    newArr[position] = after
    return newArr.join(" ")
  }

had to look up the correction painful but found a fix
