- Clone down this repo.
- Complete the functions for add, divide, multiply and subtract
- Use node modules to require and export all the functions
- We will add to this repo as we go!
- Adds two or more values
- Sum up a single array of values
- Takes an array and a value and adds that value to every item in the array and returns a NEW array (does not mutate)
add(2, 3, 4, 5) // returns 19
add([1, 5, 10]) // returns 16
add([1, 2, 3], 10) // returns array [11, 12, 13]
- Subtracts two values
- Takes an array and a value and subtracts that value to every item in the array and returns a NEW array (does not mutate)
subtract(10, 9) // returns 1
subtract([1, 2, 3], 10) // returns array [-9, -8, -7]
- Divides two values,
x / y (x = numerator, y = denominator)
- Takes an array and a value and divides that value (as the denominator) to every item in the array and returns a NEW array (does not mutate)
divide(2, 3) // returns 0.6666666666666666
divide([1, 2, 3], 3) // returns array [0.3333333333333333, 0.6666666666666666, 1]
- Adds two or more values
- Generates the product of single array of values
- Takes an array and a value and multiplies that value by every item in the array and returns a NEW array (does not mutate)
multiply(4, 5.2); // returns 20.8
multiply(2, 3, 4); // returns 24
multiply([1, 2, 3, 4]) // returns 24
multiply([5, 10, 15, 20], 5) // returns array [25, 50, 75, 100]
- Returns the absolute value of a single number
- Returns the absolute value as an array for every value in an array of numbers
- Returns the square of a single value
- Returns the square of every number in an array of numbers and returns a NEW array (does not mutate)
- Cubes a value
- Cubes an array of of values and returns a NEW array (does not mutate)
- Takes a value and exponent and returns that number raised to that exponent
- Takes an array of values and a single exponent and returns a NEW array (does not mutate) of numbers that are that value raised to the exponent
- Returns the minimum value from one or more numbers
- Returns the minimum from an array of values
- Returns the maximum value from one or more numbers
- Returns the minimum from an array of values
- Returns the average value from one or more numbers
- Returns the average from an array of values
- Computes the median from any amount of numbers
- Computes the mediam from an array of numbers
- In case of an even number of values, the average of the two middle values is returned
- Computes the mode of a any amount of numbers (the one that appears the most number of times)
- Computes the mode from an array of numbers. If there is more than one mode, it returns an array of those values.
