Math

average

Returns the average of an 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;

Math

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) =>
