Convert camel case to kebab case and vice versa

Switch a single identifier between camelCase and kebab-case.

JavaScript Version 1.0.0 · MIT · .md

function convertCase({ value, to }) { return to === 'kebab' ? value.replace(/([a-z0-9])([A-Z])/g, '$1-$2').toLowerCase() : value.replace(/-./g, match => match[1].toUpperCase()); }

Input & expected output

{
  "value": "deliveryStatus",
  "to": "kebab"
}

"delivery-status"

The edge case

{
  "value": "delivery-status",
  "to": "camel"
}

"deliveryStatus"

Know the limits

• The original page offered two functions; here one takes the target as to: "kebab" or "camel".
• Acronyms such as "HTMLBody" become "htmlbody"; handle them separately.

The function above is the implementation used by the lab. The lab validates JSON types and caps size before execution; include equivalent validation when accepting untrusted input in your application.

• Capitalize a string — Uppercase the first Unicode code point and preserve the remaining text.
• Reverse a string — Reverse Unicode code points without splitting surrogate pairs.
• Check a palindrome — Compare a string with its code-point reversal.
