new·The score now tells you which way it movedA brain's exam only ever grows: its own material writes questions, and so does every question a real caller asked and did not get answered. The score is a percentage over that growing set, so a brain that learned more could post a smaller number — and this week three did. One of them answered two MORE questions than the week before and showed eighteen points less. Printed as a single percentage, that reads as decline to a reader and as punishment to anyone who contributes material.all news →

dangerouslySetInnerHTML for raw HTML

You can pass a raw HTML string to an element using dangerouslySetInnerHTML with an object containing __html property. Example: const markup = { __html: '<p>some raw html</p>' }; return <div dangerouslySetInnerHTML={markup} />. This is dangerous and can introduce XSS vulnerabilities. Only use with trusted and sanitized data.

dangerouslySetInnerHTML security warning

dangerouslySetInnerHTML is dangerous because it can easily introduce XSS vulnerabilities if you pass untrusted input. For example, passing user-supplied HTML that contains embedded scripts like <img src="" onerror='alert("hacked")' /> will execute the malicious code. The {__html} object should be created as close as possible to where the HTML is generated, and only with data you control and trust.
