I do have a textarea element and I use angular for data-binding. I would like to capture the url in the string entered by the user, and generate a clickable live preview of that url. Any idea on how I can accomplish this using AngularJS or JavaScript? Just like Facebook.
Thanks!
You would need some server to do this for you.
You could either use a public service such as https://screenshotlayer.com/, https://www.url2png.com/
or You could run your own server with one of these libraries: https://github.com/brenden/node-webshot or https://github.com/vbauer/manet

I have a large JSON file, about 100 MB in a folder. I'd like to manually inspect some attributes, and then add more attributes to some of the objects and finally save changes and get output a modified json file.
Can someone suggest me how to do that?

I have a very simple question: when loading a web page the Page_Load function is called so that the page can be loaded. In this function can I insert some code that allows me to select and view in the browser the data present in an external database?
This answer could be of help.
You could then write a script that fetches data from a database. How you do that is a question in it self but I can recommend checking out w3schools which is good for learning plain Javascript in the beginning.

I want to make my react app able to translate to different languages simply.
I found this tutorial:
https://medium.com/#ricklee_10931/react-multi-lingual-with-react-i18next-57879f986168
I have already app that I want to add the option to translate to some languages.
Do I have to add every single text to the json and translate manually every piece of text? or there is a easier way to translate my react app?
Yes you have to add every piece of text in json file, but for translating, you can use POEditor to translate automatically

I am looking to create and then call on a function that can scan available bluetooth devices. right now I am just looking to create a function that will list all the devices. Nothing more. Is there any way to do this without referencing an html link or script?
You can't search for bluetooth devices using only javascript. You can, however, set a service that scans the devices and you read that with an api call using javascript.
please refer to this question
