Can't read JSON file using javascript

Question

I have this json file I try to read using JS but it returns a syntax error: unexpected token at line 2 ":"

Where could this error come from?

   fetch('../json/destinations_data.json')
  .then(response => response.text())
  .then(data => {
    window.alert(data);
    console.log(data);
  });

{
    "user1":{
        "email":"lucien.bramare@gmail.com",
        "password":"oss117",
        "prenom":"Lucien",
        "nom":"Bramare"
    },
    "user2":{
        "email":"noel.flantier@gmail.com",
        "password":"oss117",
        "prenom":"Noël",
        "nom":"Flantier"
    }
}

Answer 1

You're parsing it as text, not JSON.

   fetch('../json/destinations_data.json')
      .then(response => response.json()) //<-- do this!
      .then(data => {
          window.alert(data);
          console.log(data);
      });

Answer 2

Try to parse it as json and not as text

replace this

  .then(response => response.text())

with this

  .then(response => response.json())

Answer 3

You are reading json file so instead of using response.text() use response.json()

   fetch('../json/destinations_data.json')
  .then(response => response.json())
  .then(data => {
    window.alert(data);
    console.log(data);
  });

Answer 4

There is a syntax error in your json file. You have to change your format. Please check https://www.w3schools.com/js/js_json.asp

users = [
    {
       "email":"lucien.bramare@gmail.com",
       "password":"oss117",
       "prenom":"Lucien",
       "nom":"Bramare"
   },
   {
       "email":"noel.flantier@gmail.com",
       "password":"oss117",
       "prenom":"Noël",
       "nom":"Flantier"
    }
];
