Try to parse it and catch any failure. There isn’t a more fool-proof way to check if JSON is valid than that. Something like this would work:
function isValidJSON(s) {
try {
JSON.parse(s);
return true;
}
catch (e) {
}
return false;
}
// Run a few test cases:
console.log(`isValidJSON("4") = ${isValidJSON("4")}`); // prints true
console.log(`isValidJSON("[4") = ${isValidJSON("[4")}`); // prints false
console.log(`isValidJSON("[4]") = ${isValidJSON("[4]")}`); // prints true

Hi,
I need to build this carousel but I have a lot of trouble making it responsive.
What I would like is when there are 3 cards in a slide when the button is pressed all 3 of them move out of the container and on mobile if there is only one card when the button is pressed only one should move.
I tried doing it by separating the big slide and the cards and run javascript for each using matchMedia() but I didn't even get to that as I have some other bugs.
Another problem I have is when the width of the windows is resized the first element is getting out of the view, plus for some reason, they do ..read more

Doing some great work to finally understand how to insert data into a database using JavaScript AJAX and PHP

function getComments() {
var comments = document.getEle ..read more
