how to replace 2 | by nothing?

Question

if someone could give me the correct replace for : |TEST_1608224413246_Jean_Lol| replace both | with nothing

I have already tested messagenew.replace("|", ""); but it only replace the first |

Answer 1

Using string.replace

// define let to store the test string
let s = '|TEST_1608224413246_Jean_Lol|'

// use string.replace to use regex to find and replace the | character
// | is a special character in regex so we must use \| to escape it
// using g to globally replace this means find all
// second parameter is what to replace it with empty string
s = s.replace(/\|/g, '')

// log the result as this is a demo
console.log(s)

Using string.replaceAll

// define let to store the test string
let s = '|TEST_1608224413246_Jean_Lol|'

// use string.replaceAll to find and replace the | character
s = s.replaceAll('|', '')

// log the result as this is a demo
console.log(s)

Note

This would replace any and all | not just 2, if specific number 2 is important here the regex could be updated to locate the beginning and end of string and replace them only from there.
