Can you use Arrow Function in this example? If so, what would it look like? What is the best way to do value search?
var msg = ["Orange", "Melancia", "Abobora"];
var fruta = "Melancia"
buscar(fruta);
function buscar(str){
if(msg.indexOf(str) > -1){
console.log(str);
}else{
console.log("Fruta não encontrada");
}
}It would look like this:
var lista = ["Orange", "Melancia", "Abobora"];
const buscar = str => (lista.indexOf(str) > -1) ? console.log('Encontrada') : console.log("Não encontrada");
buscar("Melancia");
buscar("Não existe"); You can also use the includes() method. , but according to the documentation it is still in testing and there may be changes in syntax and behavior.

var lista = ["Orange", "Melancia", "Abobora"];
const buscar = str => (lista.includes(str)) ? console.log('Encontrada') : console.log("Não encontrada");
buscar("Melancia");
buscar("Não existe");var msg = ["Orange", "Melancia", "Abobora"];
var buscar = nome => msg.filter((elemento) => elemento.toLowerCase() === nome.toLowerCase())
invoking function
buscar("Melancia")
