How do I get / answer the callback here?
const arr = ["Lucas"];
function minhaCall(sobrenome, indice) {
return indice + 1 + ") " + sobrenome + " de Carvalho";
}
arr.forEach(minhaCall)
For example, I can not give console.log(arr.forEach(minhaCall))
How would I use the return of this function?
Apparently you want to generate a new array from strings from the original. If this is the case, this is done with Array.map , not Array.forEach .
I recommend reading each one's documentation for more details:
So, I would stay:
const arr = ["Lucas"];
function minhaCall(sobrenome, indice) {
return indice + 1 + ") " + sobrenome + " de Carvalho";
}
console.log(arr.map(minhaCall));Or in a simplified way:
const arr = ["Lucas"];
const novoArr = arr.map((nome, i) => '${i+1}) ${nome} de Carvalho');
console.log(novoArr);Your question was not clear, but I think you're trying to do something like this:
const arr = ['Lucas']
const minhaCall = (sobrenome, indice) => '${indice + 1}) ${sobrenome} de Carvalho'
arr.map((nome, i) => {
console.log(minhaCall(nome, i))
})
