На JavaScript Если вдруг нужно быстро сгенерить символьные ID, которые представляют собой сочетание цифр и символов, при этом вам не нужна высокая надежность и коллизии вам не страшны, то можно сделать это очень быстро следующим образом:

const id = f${(~~(Math.random()*1e8)).toString(16)}; // Result: f5d47a64 Можно так же сделать генерацию хешей от времени:

const id = f${(+new Date).toString(16)};

# put this in your .bash_profile
if [ $ITERM_SESSION_ID ]; then
  export PROMPT_COMMAND='echo -ne "\033];${PWD##*/}\007"; ':"$PROMPT_COMMAND";
fi

# Piece-by-Piece Explanation:
# the if condition makes sure we only screw with $PROMPT_COMMAND if we're in an iTerm environment
# iTerm happens to give each session a unique $ITERM_SESSION_ID we can use, $ITERM_PROFILE is an option too
# the $PROMPT_COMMAND environment variable is executed every time a command is run
# see: ss64.com/bash/syntax-prompt.html

Difference between Debounce and Throttle

Debounce

Debounce a function when you want it to execute only once after a defined interval of time. If the event occurs multiple times within the interval, the interval is reset each time.
Example A user is typing into an input field and you want to execute a function, such as a call to the server, only when the user stops typing for a certain interval, such as 500ms.

Throttle

sshmyg

var E = {
    createEvent: function(e, keyValue, keyCode) {
        e = e || 'keypress';

        keyValue = keyValue ? keyValue.charCodeAt(0) : keyCode;

        if (!(e || keyValue)) {
            throw Error('e and keyValue required');
        }

var extend = function(target, source) {
    target = target || {};
    
    for (var prop in source) {
        if (!source.hasOwnProperty(prop)) continue;

        if (typeof source[prop] === 'object') {
            target[prop] = extend(target[prop], source[prop]);
        } else {
            target[prop] = source[prop];
