Random integer in range

Generates a random integer in the specified range.

• Use Math.random() to generate a random number and map it to the desired range.
• Use Math.floor() to make it an integer.

const randomIntegerInRange = (min, max) =>
  Math.floor(Math.random() * (max - min + 1)) + min;

randomIntegerInRange(0, 5); // 2
