converting JSON values into an array of strings in JavaScript

Greetings to all! I am excited to be a part of this community as I embark on my programming journey. I haven't been able to find any information on this particular topic, so I've taken the initiative to start a new discussion. If anything seems off or incorrect, please don't hesitate to let me know.

Now, onto the main issue at hand - I am faced with a challenge. I am looking to extract the values from a JSON object and store them in a string array using Javascript.

The JSON object I have is structured like this:

{"prop1":"hello","prop2":"world!"}

What I aim to achieve is a string array that looks like this:

stringarray = [hello, world];

How can I efficiently retrieve the values (hello & world) from the JSON object and place them into a string array without including the special characters (", :) and excluding the properties (prop1, prop2)?

Go through each key and add the corresponding values to an array:

var stringarray = [];
for (var k in info) {
    stringarray.push(info[k]);
}

Iterate over the attributes of an object using a for loop

var myObject = {"name":"John","age":30};
var valueArray = [];
for(var property in myObject){
    valueArray.push(myObject[property]);
}

One innovative technique that is worth picking up involves manipulating a JSON data converted into a JavaScript object:

Object.keys(data).map(function(key) { return data[key]; });

The process here is to utilize Object.keys to generate an array containing all the keys in the object, resulting in something like ['property1', 'property2']. Next, we apply the convenient map function on arrays to alter each element within that array using a designated function, which in this case retrieves the value associated with that key from the object.

This can be compacted into a nifty little function as shown below:

function extractObjectValues(data) {
    return Object.keys(data).map(function(key) { return data[key]; });
}

It may seem surprising, but such functionality is not inherently included in JavaScript; however, the Underscore library provides something similar with _.values.

With this implementation, you could easily execute something simple like this:

extractObjectValues(JSON.parse(jsonData))
