 [[2, 6, 'a'], [8, 4, 6], [10]].map(x => firstTwoMax(...x)); // [6, 8, 10]
 
call
Given a key and a set of arguments, call them when given a context. Primarily useful in composition.
Use a closure to call a stored key with stored arguments.
const call = (key, ...args) => context => context[key](...args);

palindrome

-
Returns true if the given string is a palindrome, false otherwise.

-
Convert string String.toLowerCase() and use String.replace() to remove non-alphanumeric characters from it.
-Then, String.split('') into individual characters, Array.reverse(), String.join('') and compare to the original, unreversed string, after converting it String.tolowerCase().

-
const palindrome = str => {
-  const s = str.toLowerCase().replace(/[\W_]/g, '');
-  return (
-    s ===
-    s
-      .split('')
-      .reverse()

RGBToHex

+
Converts the values of RGB components to a color code.

+
Convert given RGB parameters to hexadecimal string using bitwise left-shift operator (<<) and toString(16), then String.padStart(6,'0') to get a 6-digit hexadecimal value.

+
const RGBToHex = (r, g, b) => ((r << 16) + (g << 8) + b).toString(16).padStart(6, '0');
+
RGBToHex(255, 165, 1); // 'ffa501'

-
Gets n random elements at unique keys from array up to the size of array.

-
Shuffle the array using the Fisher-Yates algorithm.
-Use Array.slice() to get the first n elements.
-Omit the second argument, n to get only one element at random from the array.

-
const sampleSize = ([...arr], n = 1) => {
-  let m = arr.length;

+
Use setTimeout() and clearTimeout() to throttle the given method, fn.
+Use Function.apply() to apply the this context to the function and provide the necessary arguments.
+Use Date.now() to keep track of the last time the throttled function was invoked.
