I have this array "Group":

i would like to have the value of name (test01) but i have undefined with console.log(group['name']), console.log(group[name]) or console.log(group.name).

How i can display the value ?

Answer 1

It's an array of objects - access the specific object first using group[0] then access the property you want with group[0].name .

 const group = [{ name: "test01" }]; const res = group[0].name; console.log(res); 

Answer 2

Based on what you have you can call your propriety if it's an object or an array of objects.

 const object = { name: "test1", group: "c2" } console.log(object.name) const array = [{ name: "test1", group: "c2" }] console.log(array[0].name)
