encodeURIComponent encodes all special characters including structural URL characters like / ? # — use it for encoding a single query string value. encodeURI leaves those structural characters intact — use it for encoding a full URL.

URL Encoding and HTTP Status Codes in One Place
URL encoding (percent-encoding) is something every developer encounters constantly — in query strings, API parameters, redirect targets, and form submissions. This tool encodes and decodes both URL components and full URLs, and also parses any URL into its scheme, host, path, query parameters, and fragment for easy inspection.
The HTTP Status Code Reference covers all standardised codes from 100 to 511, searchable by code number or keyword, filterable by class (1xx through 5xx), with plain-English descriptions and notes on the most commonly encountered codes.

FAQsURL Encoder & HTTP Status Codes
What is the difference between encodeURIComponent and encodeURI?
What is the difference between 301 and 308?
Both are permanent redirects. 301 allows the browser to change the request method (POST to GET), while 308 requires the same method to be used. Use 308 when permanently redirecting POST requests.
What is the difference between 401 and 403?
401 means not authenticated (the server doesn't know who you are). 403 means not authorised (the server knows who you are but you don't have permission).
