My solution to "how list all students with the same name" and print "student not found" message (in portuguese).

// *** estudantes.js:

var estudantes = [ { name: 'João', track: 'JavaScript', achievements: 'ABC', points: 123 }, { name: 'José', track: 'HTML', achievements: 'A+', points: 456 }, { name: 'José', track: 'PHP', achievements: 'A+', points: 789 }, { name: 'Josué', track: 'Java', achievements: '0-', points: 5 }, { name: 'Mathias', track: 'MongoDB', achievements: '0---', points: 2 } ]; var mensagemHTML = ''; var nomeProcurado = '';

function printDOM(mensagem) { var divID = document.getElementById('saida'); divID.innerHTML = mensagem; }

function prepararMSG(indice) { mensagemHTML += '<ol>'; for (var key in estudantes[indice]) { mensagemHTML += '<li>' + key + ': ' + estudantes[indice][key] + '</li>'; } mensagemHTML += '</ol>'; }

while (true) { nomeProcurado = prompt('Digite o nome do aluno ou \'sair\' para sair:'); if (nomeProcurado.toLowerCase() !== "sair") { mensagemHTML = ''; for (var i=0; i<estudantes.length; i++){ if (nomeProcurado === estudantes[i].name) { prepararMSG(i); } } if (mensagemHTML === '') { mensagemHTML = 'O aluno ' + nomeProcurado + ' não foi encontrado.' } printDOM(mensagemHTML); } else { break; } }

// *** index.html:

<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Projeto 2</title> <link rel="stylesheet" href="css/styles.css"> </head> <body> <h1>Lista de Alunos:</h1> <div id="saida">

</div> <script src="js/estudantes.js"></script> </body> </html>
