Convert camelCaseText to Sentence Case Text

Question

How can I convert a string either like \'helloThere\' or \'HelloThere\' to \'Hello There\' in JavaScript?

Answer 1

Based on one of the examples above I came up with this:

const camelToTitle = (camelCase) => camelCase
  .replace(/([A-Z])/g, (match) => ` ${match}`)
  .replace(/^./, (match) => match.toUpperCase())
  .trim()

It works for me because it uses .trim() to handle the edge case where the first letter is capitalized and you end up with a extra leading space.
