Convert a string into a camel case

1. Using regular expression
2. Using lodash

1. Using regular expression

In this method, we’ll use the Regular Expression, `toLowerCase()` and `toUpperCase()` methods to convert a string into a camel case.

function camelCase(str) {
  return str.replace(/(?:^\w|[A-Z]|\b\w|\s+)/g, function(match, index) {
    if (+match === 0) return ""; // or if (/\s+/.test(match)) for white spaces
    return index === 0 ? match.toLowerCase() : match.toUpperCase();
  });
}

camelCase("Clue mediator"); // Output: clueMediator
camelCase("hello world"); // Output: helloWorld

2. Using lodash

In this second method, we will use the `camelCase()` function from the lodash. Don’t forget to add the lodash script in the page.

camelCase("Clue mediator"); // Output: clueMediator
camelCase("hello world"); // Output: helloWorld

That’s it for today.
