  1. Here, above we show you an example in JavaScript.
  2. We can also use basic HTML codes here to use this iteration inside HTML codes. We hope you all know what is the basic HTML structure and how to write this JavaScript code inside HTML tags.
  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. Now, as we see inside these tags we see that array of JSON data is stored inside a constant. And we have to access the data of that object. So, for this we just use JSON.parse() method to on that constant. And store the data inside a variable After this we just use for loop to get the data one by one and display it with help of the console. Without whole data, we can also get the data inside specific columns or variables or keys to display.
  5. In the second example, we see that there is a multidimensional array. In last, in the example, we understand how to parse JSON data in a single-dimensional array.
  6. Now, to use parse in multidimensional we use this example. And in this, we use the same concept of JSON.parse() in this example as the above example and after this, we use the period to access the required data instead of the index.
  7. For reference, you can also see the above example, With help of this, we can also get the data inside the single column inside of the whole data.
