An Introduction to JSON

Hi, It’s not a comment it’s a question I’m a beginner in this language and i have some knowledgement in JavaScript. I should like to change the link in a JSon file, but i ignore the syntax. The line is : “id”: “1”, “link”: “#”, “src”: “https://picsum.photos/1920/776/?random”,

I should like to change the “src”: “http…” by a picture in a file in my server. What do I have to write ?

Many Thanks for your help Best regards CP

Thanks for writing this, very clear and well-written. I’m an amateur, new to Javascript and just heard of JSON recently. It seems like a very good thing, but I’m not sure where or when to use it. I’ve been experimenting on a project using PHP to get data from a mysql server database, and learned from an online course how to make tables in PHP to display the data on a website. I like the fact that the PHP is not viewable (as tho I wrote all those table rows by hand!). So I’m not sure how or why I would use JSON if PHP is already sending and formatting the data. However, I do foresee tying to live-update the table as data is added, which I understood AJAX to be used for, so I’m wondering if JSON is just a non-XML version of AJAX? And would it seem to you that JSON would help me achieve that instead of or along with PHP? Can you show me sample code to make use of JSON from a PHP (or whatever) file? Thanks in advance Nate

Hey, found your article while surfing on info about learning JSON, maybe you should expand your article like guys did here - https://developer.mozilla.org/en-AU/docs/Learn/JavaScript/Objects/JSON

Great article. Concise and very clear. I am curious if there is currently a way to export Excel data directly to JSON, instead of to .csv and then converting using a separate utility? Thanks

Quiet useful for beginner!

Quite useful for beginner! jsonlint.com is great tool to validate json format,and i also use jsonhome.com to edit/format json.
