Math

approximatelyEqual

Checks if two numbers are approximately equal to each other.

Use Math.abs() to compare the absolute difference of the two values to epsilon. Omit the third parameter, epsilon, to use a default value of 0.001.

const approximatelyEqual = (v1, v2, epsilon = 0.001) => Math.abs(v1 - v2) < epsilon;
 
approximatelyEqual(Math.PI / 2.0, 1.5708); // true
-

average

Returns the average of two or more numbers.

Use Array.reduce() to add each value to an accumulator, initialized with a value of 0, divide by the length of the array.

const average = (...nums) => [...nums].reduce((acc, val) => acc + val, 0) / nums.length;
+

average

Returns the average of two or more numbers.

Use Array.reduce() to add each value to an accumulator, initialized with a value of 0, divide by the length of the array.

const average = (...nums) => nums.reduce((acc, val) => acc + val, 0) / nums.length;
 
average(...[1, 2, 3]); // 2
 average(1, 2, 3); // 2

averageBy

Returns the average of an array, after mapping each element to a value using the provided function.

Use Array.map() to map each element to the value returned by fn, Array.reduce() to add each value to an accumulator, initialized with a value of 0, divide by the length of the array.

const averageBy = (arr, fn) =>
