Javascript question

Question

Is there any way to have javascript save a new variable and saves it in the code for instance var = new() let = "ok". Creates a new variable in the script file forever.

Answer 1

No, JavaScript cannot save any data on file.

Answer 2

For globally accessed data, you need to use ajax to update data on server, you also need to develop server script, eg php or nodejs, and also setup database on server.

So JavaScript run from front end, ajax data to php on backend server, php script then updata data to database mysql.

Answer 3

How would I do this then?

Answer 4

Do that with a cookie
