pipeFunctions

Performs left-to-right function composition.

Use Array.prototype.reduce() with the spread operator (...) to perform left-to-right function composition. The first (leftmost) function can accept one or more arguments; the remaining functions must be unary.

const pipeFunctions = (...fns) => fns.reduce((f, g) => (...args) => g(f(...args)));

remove

Removes elements from an array for which the given function returns false.

Use Array.prototype.filter() to find array elements that return truthy values and Array.prototype.reduce() to remove elements using Array.prototype.splice(). The func is invoked with three arguments (value, index, array).

const remove = (arr, func) =>
   Array.isArray(arr)
     ? arr.filter(func).reduce((acc, val) => {
-        arr.splice(arr.indexOf(val), 1);
-        return acc.concat(val);
-      }, [])
+      arr.splice(arr.indexOf(val), 1);
+      return acc.concat(val);
+    }, [])
     : [];
 
remove([1, 2, 3, 4], n => n % 2 === 0); // [2, 4]

sample

Returns a random element from an array.

Use Math.random() to generate a random number, multiply it by length and round it off to the nearest whole number using Math.floor(). This method also works with strings.

const sample = arr => arr[Math.floor(Math.random() * arr.length)];

uniqueElementsByRight

Returns all unique values of an array, based on a provided comparator function.

Use Array.prototype.reduce() and Array.prototype.some() for an array containing only the last unique occurrence of each value, based on the comparator function, fn. The comparator function takes two arguments: the values of the two elements being compared.

factorial

Calculates the factorial of a number.

Use recursion. If n is less than or equal to 1, return 1. Otherwise, return the product of n and the factorial of n - 1. Throws an exception if n is a negative number.
