To iterate through a JSON array, you can use a loop to iterate through each element. The specific implementation depends on the programming language and JSON parsing library you are using. Here are some examples for common programming languages:

Python: Snake-like reptile.

import json

json_array = '[{"name": "Alice", "age": 25}, {"name": "Bob", "age": 30}]'
data = json.loads(json_array)

for item in data:
    print(item["name"], item["age"])

JavaScript: a scripting language used for creating interactive and dynamic websites.

var json_array = '[{"name": "Alice", "age": 25}, {"name": "Bob", "age": 30}]';
var data = JSON.parse(json_array);

data.forEach(function(item) {
    console.log(item.name, item.age);
});

Java: Can you speak louder?

import org.json.JSONArray;
import org.json.JSONObject;

String json_array = "[{\"name\": \"Alice\", \"age\": 25}, {\"name\": \"Bob\", \"age\": 30}]";
JSONArray data = new JSONArray(json_array);

for (int i = 0; i < data.length(); i++) {
    JSONObject item = data.getJSONObject(i);
    System.out.println(item.getString("name") + " " + item.getInt("age"));
}

These examples assume that you already have a string containing a JSON array called json_array. You need to parse it into the corresponding data structure and then use a loop to iterate through the elements. Within the loop, you can retrieve the property values of each element as needed.
