How can an array be concatenated using tabs?

Question

How can an array be concatenated using tabs?

I am currently in the process of integrating with an old system that requires a value to be sent via a GET request as a tab delimited string. I have my data stored in an array, but I am facing difficulty when attempting to properly format it using the join() method.

I have tried several approaches, none of which seem to work as intended;

var myArray = ["a", "b", "c"]

myArray.join(\t);
myArray.join(/\t/);
myArray.join('\t');
myArray.join('\\t');
myArray.join('   '); // tab character

Edit

Upon further investigation, it seems that the issue arises when attempting to URL encode the tab delimiter. Instead of converting the tab into %09, it is simply being removed from the output.

Desired URL encoded var:

"?tags=a%09b%09c"

Actual output:

"?tags=abc"

If anyone has insights on how to resolve this issue, please share your knowledge!

The issue you're facing is that you need to assign the result of the Join() method to a new variable. The original variable remains unchanged. To resolve this, consider the following code snippet:

var myArray = ["a", "b", "c"]

var arrayToString = myArray.join('\t');

alert(arrayToString);

\t can be utilized...

let numbers = [4, 5, 6];
let string = numbers.join("\t");

However, it is important to consider how your output will be displayed. When adding the content to a regular HTML page, the tabs might appear as spaces. You can overcome this by placing the content within special elements like <pre>.

In cases where multiple spaces are needed, resorting to using several instances of   could be a workaround...

let numbers = [4, 5, 6];
let string = numbers.join("&nbsp;&nbsp;&nbsp;&nbsp;"); // my apologies :(
