JavaScript: Convert radians to degrees
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

Sample Solution-2:
JavaScript Code:
const radians_to_degrees = rad => (rad * 180.0) / Math.PI;
console.log(radians_to_degrees(Math.PI / 2));
console.log(radians_to_degrees(0.7853981633974483));
Sample Output:
90 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]
