  3. If you don’t know anything from the above you can visit our article, in which you can learn these concepts easily from our experienced developers.
  4. Now, let us understand the script tag. As we know the script tag is paired tag. And our JavaScript codes are always written inside these tags.
  5. Now, as we see inside these tags we see that we create an array that is on single dimensional inside JavaScript.
  6. After that, as we know that we have to parse this data. So, we just use JSON. parse() and store the result inside a variable.
