JavaScript: Pad a string on both sides with the specified character

JavaScript fundamental (ES6 Syntax): Exercise-38 with Solution

Write a JavaScript program to pad a string on both sides with the specified character, if it's shorter than the specified length.

• Use String.prototype.padStart() and String.prototype.padEnd() to pad both sides of the given string.
• Omit the third argument, char, to use the whitespace character as the default padding character.

Sample Solution:

JavaScript Code:

//#Source https://bit.ly/2neWfJ2 

const pad = (str, length, char = ' ') =>
 str.padStart((str.length + length) / 2, char).padEnd(length, char);
console.log(pad('cat', 8));
console.log(pad(String(42), 6, '0'))
console.log(pad('foobar', 3))

Sample Output:

  cat   
004200
foobar
