String to non-array json

Question

I have a string that looks like the following:

 {
 "results": [
 {
 "address_components": [
 {
 "long_name": "Ireland",
 "short_name": "Ireland",
 "types": [
 "establishment",
 "natural_feature"
 ]
 }
 ],
 "formatted_address": "Ireland",
 "geometry": {
 "bounds": {
 "northeast": {
 "lat": 55.38294149999999,
 "lng": -5.431909999999999
 },
 "southwest": {
 "lat": 51.4475448,
 "lng": -10.4800237
 
 }
 }],
 "status" : "OK"
 }

I want to turn this into a json that I can easily traverse. However when I call JSON.parse() on this string I get a json array that is a pain to traverse. I want to be able to extract the lat and lng from northeast without having to loop through the entire array.

• Barmar: What do you mean by turn it into a JSON? If it's a string, it's already a JSON. If you parse it, you get an object, not a JSON.
• Barmar: What if there are multiple elements in the results array? How will you get all the lat and lng without looping?
• VLAZ: There is one single item in the array. You can just use [0]. If there is more than one item, you will have multiple lat/long values anyway, so you'd need iteration of some description.
• AlexSp3: If the result key is an array I cannot figure another way to do it without a loop
• Barmar: object.results[0].geometry.bounds.northeast.lat

Answer 1

 var json = `{
 "results": [
 {
 "address_components": [
 {
 "long_name": "Ireland",
 "short_name": "Ireland",
 "types": [
 "establishment",
 "natural_feature"
 ]
 }
 ],
 "formatted_address": "Ireland",
 "geometry": {
 "bounds": {
 "northeast": {
 "lat": 55.38294149999999,
 "lng": -5.431909999999999
 },
 "southwest": {
 "lat": 51.4475448,
 "lng": -10.4800237
 }
 }
 }
 }
 ],
 "status" : "OK"
}`;
var data = JSON.parse(json);
var bounds = data.results[0].geometry.bounds;
var bound = bounds.northeast || bounds.southwest;
console.log(bound.lat, bound.lng);

If you know northeast is always an option you can simplify this to:

console.log(data.results[0].geometry.bounds.northeast);

That will give you your lat and lng.
