Difference between escape(), encodeURI(), encodeURIComponent()

Question

In JavaScript, what is the difference between these?

1. escape() / unescape()
2. encodeuri() / decodeuri()

Answer 1

• escape — broken, deprecated, do not use
• encodeURI — encodes characters that are not allowed (raw) in URLs (use it to fix up broken URIs if you can't fix them beforehand)
• encodeURIComponent — as encodeURI plus characters with special meaning in URIs (use it to encode data for inserting into a URI)
