how can one cycle through this demonstration

Within my code, there is a variable called "data" which holds an array of objects:

[{"id_questao":1,"id_tipoquestao":1,"conteudo":"Pergunta exemplo 1","id_formulario":1},{"id_questao":2,"id_tipoquestao":1,"conteudo":"Pergunta exemplo 2","id_formulario":1}]

I am looking to loop through the "data" array and extract the id_questao, id_tipoquestao, and conteudo from each object. What would be the correct approach to achieve this?

Answer №1

Utilize o método Array.forEach juntamente com a desestruturação de objetos

var arr = [{"id_questao":1,"id_tipoquestao":1,"conteudo":"Pergunta exemplo 1","id_formulario":1},{"id_questao":2,"id_tipoquestao":1,"conteudo":"Pergunta exemplo 2","id_formulario":1}];

arr.forEach(({id_questao, id_tipoquestao, conteudo})=>{
  console.log(id_questao+" "+id_tipoquestao+ " "+conteudo);
});

`

Answer №2

To extract specific values from an array, you can leverage the map() method. Let's assume your array is named arr.

var newArr = arr.map(item => {item.id_questao, item.id_tipoquestao, item.conteudo})

The variable newArr now holds these values extracted from each index of the original array arr.
