How to Use Regular Expressions

At a glance

The community member in the post is asking how to identify a pattern in regex and save it in a variable. In the comments, another community member provides a solution using a function extrairCPFDaString() that extracts an 11-digit CPF (Brazilian ID number) from a given text and saves it in a variable. The solution is well-received by another community member who says "Yep, good job!".

Solved with this code:

function extrairCPFDaString(texto) {
const regexCpf = /\b\d{11}\b/;
const resultado = texto.match(regexCpf);

if (resultado) {
const cpfEncontrado = resultado[0];
return cpfEncontrado;
} else {
return "CPF não encontrado no texto.";
}
}

const texto = "CPF: 12234455566\nWhatsApp: +556791440690";
const resultadoExtracao = extrairCPFDaString(texto);

return (resultadoExtracao);
