Thinful JavaScript number functions

// Create a function called computeArea that takes two arguments: width and height. 
// It returns the area of a rectangle whose width is width and height is height. 
// So computeArea(2, 2) would return 4, and computeArea(3, 5) would return 15.
const computeArea = (width, height) => width * height;

// Create 2 functions, one called celsToFahr that converts Celsius to Fahrenheit and
// another called fahrToCels that converts Fahrenheit to Celsius. celsToFahr takes one 
// argument, celsTemp, and fahrToCels takes one argument, fahrTemp.
// [°F] = [°C] × ​9⁄5 + 32
// [°C] = ([°F] − 32) × ​5⁄9

const celsToFahr = celsTemp => (celsTemp * (9 / 5)) + 32

const fahrToCels = fahrTemp => (fahrTemp - 32) * (5 / 9)

// Write a function called isDivisible that takes 2 arguments: divisee and divisor. 
// This function should return true if divisee can be divided by divisor with no remainder, 
// otherwise, it should return false. So isDivisible(18, 3) should be true, while isDivisible(15, 4) 
// should be false.

const isDivisible = (divisee, divisor) => divisee % divisor === 0 ? true : false;
