Frequently Asked Questions
What's the difference between URL encoding and URL component encoding?
encodeURI() encodes characters that have special meaning in URLs but leaves characters like :, /, ?, # intact. encodeURIComponent() encodes all characters that could be problematic.
When should I use Base64 encoding?
Base64 is useful for encoding binary data or when you need to transmit data that might contain special characters through text-only channels.
What is form data encoding?
Form data encoding properly encodes key-value pairs for URL query strings or form submissions, handling special characters in both keys and values.
