Utility functions that I find useful.
Utility functions for ArrayBuffer like Base64 conversion using browser apis.
Merges two arrays into one and removes duplicates
Converts html attributes to boolean and back.
Clamp a value between min and max (inclusive).
Returns a function, that, as long as it continues to be invoked, will not
be triggered. The function will be called after it stops being called for
N milliseconds. If immediate is passed, trigger the function on the
leading edge, instead of the trailing.
Encrypts and decrypts a string using native browser apis.
For simplicity only 'AES-GCM' and 'AES-CBC' algorithms are implemented.
There is a random 'AES-GCM' key generator and one that derives a key from a password and salt.
Extracts the content from the body of a Response object either
as json (if Content-Type=application/json),
as text (if Content-Type=text/*),
or as a Blob if all else fails.
Wrapper around Json.parse() to catch any errors and return a Promise.
The synchronous version returns an Object with data and error properties.
If the parsing failed the error is set. Otherwise it is undefined.
Maps a value in an input range to an output range.
Converts an unsigned byte sized integer into its hex representation.
Compress or decompress a string with native browser APIs with 'gzip', 'deflate', or 'deflate-raw'. Compatible to use with atob and btoa.
Returns a function, that, as long as it continues to be invoked, will only
trigger every N milliseconds. If immediate is passed, trigger the
function on the leading edge, instead of the trailing.
There is also a version that uses requestAnimationFrame().
It might be worth noting the difference between throttling and debouncing, as the terms are often confused.
- A debounced function is called only once in a given period, delay milliseconds after its last invocation (the timer is reset on every call).
- Whereas a throttled function is limited to be called no more than once every delay milliseconds.
