Throttle any function with a namespace. Named allows to throttle a same function differently depending on a name.

named_throttle.js

// Normal throttle for a normal function call
function throttle(func, delay) {
    let timeout;
    return function(...args) {
        if (!timeout) {
        timeout = setTimeout(() => {
            func.call(this, ...args)
            timeout = null
        }, delay)
        }
    }
}

// Named throttle for a same function called in different cases (different errors)
function named_throttle(func, delay) {
    let timeouts = {};
    return function(name, ...args) {
        if (!timeouts[name]) {
        timeouts[name] = setTimeout(() => {
            func.call(this, ...args)
            timeouts[name] = null
        }, delay)
        }
    }
}

let throttled_log = named_throttle(console.log, 2000);
throttled_log("first_log_type", 1,2,3);
throttled_log("first_log_type", 1,2,3);
throttled_log("first_log_type", 1,2,3);
throttled_log("second_log_type", 2,2,"two");
throttled_log("second_log_type", 2,2,"two");

> 1 2 3
> 2 2 "two"
