JavaScript Math: Exercise-34 with Solution

Write a JavaScript function to convert radians to degrees.

Test Data : console.log(radians_to_degrees(0.7853981633974483));
45

Sample Solution-1:

JavaScript Code:

function radians_to_degrees(radians)
{
  var pi = Math.PI;
  return radians * (180/pi);
}
          
console.log(radians_to_degrees(0.7853981633974483));

Sample Output:

45

JavaScript: Tips of the Day

Randomizes the order of the values of an array, returning a new array

Example:

const tips_shuffle = ([...arr]) => {
  let x = arr.length;
  while (x) {
    const i = Math.floor(Math.random() * x--);
    [arr[x], arr[i]] = [arr[i], arr[x]];
  }
  return arr;
};
const foo = [2, 4, 6];
console.log(tips_shuffle(foo));

Output:

[4, 2, 6]
