Get index of an object inside of an array with JS

Question

I was making a js code that gets objects from an array. I just want to have a script that takes the object index and prints it on the html page. I tried many different things but nothing is working. For example, let's say that first {} is 0, then the second one with rate 3.3 is 1... Here is a jsfiddle : https://jsfiddle.net/76e40vqg/1/

var data = [{"image":"link1","name":"Name1","address":"Address1","rate":"4.4"},{"image":"link2","name":"Name2","address":"Address2","rate":"3.3"},{"image":"link3","name":"Name3","address":"Address3","rate":"3.2"}
];
var restoName = [];
for(i = 0; i < data.length; i++){ 
 if(restoName.indexOf(data[i].name) === -1){
 restoName.push(data[i].name); 
 } 
}
var restoAddress = [];
for(i = 0; i < data.length; i++){ 
 if(restoAddress.indexOf(data[i].address) === -1){
 restoAddress.push(data[i].address); 
 } 
}
var restoRate = [];
for(i = 0; i < data.length; i++){ 
 if(restoRate.indexOf(data[i].rate) === -1){
 restoRate.push(data[i].rate); 
 } 
}
var restoImage = [];
for(i = 0; i < data.length; i++){ 
 if(restoImage.indexOf(data[i].image) === -1){
 restoImage.push(data[i].image);
 } 
}
for(i = 0; i < restoName.length; i++){
document.getElementById('output').innerHTML += "Image : <a href='" + restoImage[i] + "'><div class='thumb' style='background-image:" + 'url("' + restoImage[i] + '");' + "'></div></a><br>" + "Name : " + restoName[i] + "<br>" + "Address : " + restoAddress[i] + "<br>" + "Rate : " + restoRate[i] + "<br>" + "Index" + "<br><hr>";
 }

Thank you

• T.J. Crowder: There's no JSON above. JSON is a textual notation for data exchange. (More) If you're dealing with JavaScript source code, and not dealing with a string, you're not dealing with JSON.
• Toufic Batache: So what is the data = [{object:object}] called?
• Nina Scholz: it's called an array of objects.
• Toufic Batache: Changed it right now. Thanks for your edit

Answer 1

I think you are missing ..."Index" + i +"<br>...

@Nina Scholz 's solution is working too.

• Toufic Batache: Thank you both so much, but I can't accept 2 answers.
• Luigi Cerone: Don't worry , @Nina Scholz is better! :) It is clean code.
• Toufic Batache: You too are good. You know that it worked first with your comment not Nina. If you want I can accept yours as it's the one which help.
• Luigi Cerone: Do what you think it's better to do :) Have a nice day!
• Toufic Batache: Thanks. Have a nice day too

You could use just a single loop for showing the data with Array#forEach.

The forEach() method executes a provided function once per array element.

var data = [{ image: "link1", name: "Name1", address: "Address1", rate: "4.4" }, { image: "link2", name: "Name2", address: "Address2", rate: "3.3" }, { image: "link3", name: "Name3", address: "Address3", rate: "3.2" }];
data.forEach(function (object, index){
 console.log('index', index);
 console.log('image', object.image);
 console.log('name', object.name);
 console.log('address', object.address);
 console.log('rate', object.rate);
 console.log('--');
});

Traditional with for loop and an index i.

var data = [{ image: "link1", name: "Name1", address: "Address1", rate: "4.4" }, { image: "link2", name: "Name2", address: "Address2", rate: "3.3" }, { image: "link3", name: "Name3", address: "Address3", rate: "3.2" }],
 i;
for (i = 0; i < data.length; i++) {
 console.log('index', i);
 console.log('image', data[i].image);
 console.log('name', data[i].name);
 console.log('address', data[i].address);
 console.log('rate', data[i].rate);
 console.log('--');
}

• Toufic Batache: This does't show me the index of each element. It just gets the elements and prints them.
• Toufic Batache: It doesn't seem to work could you edit my fiddle so I see how it works? Thanks
• Nina Scholz: view here for index, just add i for the output.
• Toufic Batache: Yeah, i was the solution, at first it was index, index. The second code is the one working... Thanks
