How to insert value after specific text in the string

I would like to add value to my URL after the specific text. How I can achieve this?

I found a solution where I can slice and add values but I don't have the index fixed in this URL.

const url = 'www.website.com/api/test1/test2';

const url = 'www.website.test.com/api/test1/test2/test3';

const output1 = 'www.website.com/api/ha/test1/test2';

const output2 = 'www.website.test.com/api/ha/test1/test2/test3';

I prefer working with URL

const url1 = new URL('https://www.website.com/api/test1/test2');
const pn =  url1.pathname.split("/")
pn.splice(2,0,'ha')
url1.pathname=pn.join("/");
console.log(url1.href)

If you want to add a certain value after a certain string you can simply replace the known value with the new string:

url.replace('/api', '/api/ha')

If you don't have a fixed index, you should use Regex to search the string. Could look like this:

/(www.\D+\/api\/)[\D\d\/]+/gm

This code would put the before and after into a group and you can then do

group1 + yourstring + group2

to add it together.
