ALT Screenshot of the DevTok app on a phone with a dark brown background, showing the first post of the day with a progress bar of 12 segments at the top. The post is tagged JavaScript, Beginner, 30 sec read, and titled "const, let, var: which one?". It advises using const by default, let when you must reassign, and avoiding var. A code block shows const price = 20 and let count = 0 being updated. A "Try it" tip, Save and Got it buttons, and a Today, Library, Saved navigation bar appear below.

ALT Screenshot of the DevTok app on a phone with a dark brown background. A post tagged JavaScript, Intermediate, 30 sec read is titled "textContent vs innerHTML: a security gap". It explains that innerHTML parses a string as HTML, so user comments can run scripts, while textContent treats everything as plain text. Below is a short JavaScript code block showing box.innerHTML = comment marked risky and box.textContent = comment marked safe. Save and Got it buttons sit at the bottom, above a Today, Library, Saved navigation bar.
