 All major browsers support encoding and decoding strings in various ways leveraging the Dev Tools Console and JavaScript functionality:
 
-- Base64 encode: `btoa("string-to-encode")`
-- Base64 decode: `atob("string-to-decode")`
-- URL encode: `encodeURIComponent("string-to-encode")`
-- URL decode: `decodeURIComponent("string-to-decode")`
-- HTML encode: `escape("string-to-encode")`
-- HTML decode: `unescape("string-to-decode")`
+- base64 encode: `btoa("string-to-encode")` & base64 decode: `atob("string-to-decode")` - built-in JavaScript functions that are used to encode a string to base64 and decode a string from base64.
+- URL encode: `encodeURIComponent("string-to-encode")` & URL decode: `decodeURIComponent("string-to-decode")` - It encodes and decodes user-supplied input that will be used as a part of a URL, and it encodes all characters that have special meanings in a URL, including reserved characters.
+- URI encode: `encodeURI()` and URI decode: `decodeURI()` are functions used to encode and decode a complete URI, such as query parameters, path segments, or fragments, including special characters but excluding the reserved characters such as `:/?#[]@!$'()*+,;=` which have special meanings in a URL.
