Good morning everyone. I’m starting with Javascript and I’m having a hard time removing a part of a string up to a certain point.

got the string:

"21/07/2020 16:34:42 - Adriana gomes carneiro (Comments) daniel test" OR "21/07/2020 16:34:42 - Daniel silva (Comments) COMMENT REJECTED" The name after the date will always change.

I would like to remove part of the string until "(Comments)...", keeping for example: "(Comments) COMMENT REJECTED".

Can someone help me?

One way to solve it is to use the index together with the method substring, to extract the necessary strings. Follow an example:

const linha = "21/07/2020 16:34:42 - Adriana Gomes Carneiro (Comments) TESTE DANIEL";
const idx = linha.indexOf(" (Comments) ");
const primeiraParteStr = linha.substring(0,idx);
// "21/07/2020 16:34:42 - Adriana Gomes Carneiro"
const segundaParteStr = linha.substring(idx, linha.length);
// " (Comments) TESTE DANIEL"

Note that in the variable segundaParteStr, we have a space at the beginning of the string (maybe unwanted), to remove just use the method Trim().

segundaParteStr = linha.substring(44,linha.length).trim()
