To extract a specific value from a JSON string, first parse the string into a JavaScript object using JSON.parse(). Once converted, you can easily access any property using dot notation or bracket notation. For example, suppose your JSON string is '{"name":"John", "age":30}', convert it to an object: let obj = JSON.parse(jsonString);, then access the name property using obj.name. Learn more about JSON parsing on the Wikipedia JSON page.
Sure thing! When you’re dealing with a JSON string in JavaScript, the best way to nab a specific value is by transforming that string into a JavaScript object. This is easily done with JSON.parse(). Let’s say you’ve got this JSON string: {"name": "John", "age": 30}.
Here’s how you’ll do it:
let obj = JSON.parse(jsonString);
let name = obj.name; // Access the 'name' property
That’s it! Using JSON.parse(), you’ve translated your string into a manageable object. If this helped, consider giving it a thumbs up!
