What is the process of converting a list into a JavaScript array?

Objective:

The aim is to take the tweet provided and pass it to a visualization tool to display it on the user interface.

Steps:

I currently have a 'List' displayed on my UI. I need to convert this list into a JavaScript array (so that I can use it with Visualization tools). Each field in the list has been concatenated with 'qqq' at the end for identification purposes.

Tweet:

[*high-pitched yelp* http://t.co/qaluND2Lu3qqq, neutralqqq, 0qqq,
 I checked in at Starbucks on #Yelp http://t.co/8wRVos8STjqqq, negativeqqq, -0.159316qqq,
 i would like to thank yelp for not helping me find any club around santa monica that plays progressive edm / progressive tranceqqq, positiveqqq, 0.372338qqq,
 Nice long bar table & upstairs option (@ Social Kitchen & Brewery) on #Yelp http://t.co/uhQB003NTiqqq, positiveqqq, 0.567625qqq]

Question:

How can I split the text by 'qqq' and store it in a JavaScript array?

I attempted the following code snippet:

var str = "*high-pitched yelp* http://t.co/qaluND2Lu3qqq, neutralqqq, 0qqq";
var res = str.split("qqq");

However, this method adds an extra comma (,) at the end of every 'qqq'. I'm feeling lost here.

Is there anyone who can guide me through this?

Answer №1

Update 2

To optimize the code, consider creating a fresh array that does not contain any undefined values.

let str = "*high-pitched yelp* http://t.co/qaluND2Lu3qqq, neutralqqq, 0qqq",
    myArray = str.split('qqq'),
    newArray = new Array();

for ( let i = 0; i < myArray.length; i++ ) { // Assuming array is built starting with the key 0
    // Mark any array element as undefined or nonsensical white-space
    if ( myArray[i] !== "" && myArray[i] !== undefined && myArray[i] !== " " ) {
        newArray.push(myArray[i]);
    }
}

myArray = newArray;

console.log(myArray);
