Algorithm Spinal Tap Case

Algorithm Spinal Tap Case

Problem Explanation:

• Convert the given string to an all lowercase sentence joined by dashes.

Hint: 1

• Create a regex to for all white spaces and underscores.

Hint: 2

• You will also have to make everything lowercase.

Hint: 3

• The tricky part is getting the regex part to work, once you do that then just turn the uppercase to lowercase and replace spaces with underscores using replace()

Spoiler Alert!

Solution ahead!

Code Solution:

First solution

function spinalCase(str) {
  // Create a variable for the white space and underscores.
  var regex = /\s+|_+/g;

  // Replace low-upper case to low-space-uppercase
  str = str.replace(/([a-z])([A-Z])/g, '$1 $2');

  // Replace space and underscore with -
  return str.replace(regex, '-').toLowerCase();
}

// test here
spinalCase('This Is Spinal Tap');

🚀 Run Code

Second solution

function spinalCase(str) {
  // Replace low-upper case to low-space-uppercase
  str = str.replace(/([a-z])([A-Z])/g, '$1 $2');
  // Split on whitespace and underscores and join with dash
  return str.toLowerCase().split(/(?:_| )+/) .join('-');
}

// test here
spinalCase('This Is Spinal Tap');
