How to add a key/value pair to an existing json file?

JavaScript

The curriculum talks about how to add new key-value pairs to an object: https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/basic-javascript/add-new-properties-to-a-javascript-object

Ha!

Thank you…

So I got the data added correctly with the code shown below…

let newData = (myObject.data[textIndex2++].text2 = ${responseAItoJson});

console.log(newData);

var newData2 = JSON.stringify(myObject);

^^ However, once I run 3 cycles, and I go to create the json file, then I only come out with the last key/value pair of the last run…

How could I append/hold each value after each cycle? so, that when I go create the json file the object holds the complete information from all runs?

I got it working…

Took the initial data file out of the loop… that way it doesn’t re-loop it with the initial data all the time…

It was a simple code…

Why it took me so long??? What are my excuses???

  1. I started by trying to modify the file itself instead of converting it into an object.

  2. Unfortunately I found a bad code in the internet that I tried to copy.

  3. I forgot about ++ values to put the code in the right place.

  4. Gotta pay more attention what items I put inside my setInterval() function or I might never get it to work…

  5. I might never learn…

This can send you down a big rabbit hole. There’s lots of code out there that’s bad or a bad fit for your needs.

This stuff is complicated and takes time to learn.
