How do I covert kebab-case into PascalCase?

How could I convert this to PascalCase and to camelCase?

var text = "welcome-to-a-New-day";
toPascalCase(text); // "WelcomeToANewDAY"
toCamelCase(text); // "WelcomeToANewDAY"

Answer

A fully ES5 compatible way to do this is, to find all the dashes that are followed by an alphanumeric character using this simple regex /-w/g. Then just remove the dash and uppercase the character.

The same can be done for pascal case just by also checking for the first character in the string using ^w|-w. The rest is the same.

Here are a couple of examples:

console.log(toCamelCase("welcome-to-a-New-day"));
console.log(toPascalCase("welcome-to-a-New-day"));
console.log(toCamelCase("bsd-asd-csd"));
console.log(toPascalCase("bsd-asd-csd"));

function toCamelCase(text) {
  return text.replace(/-w/g, clearAndUpper);
}

function toPascalCase(text) {
  return text.replace(/(^w|-w)/g, clearAndUpper);
}

function clearAndUpper(text) {
  return text.replace(/-/, "").toUpperCase();
}
