In this Article we will go through how to convert a string to camelcase only using single line of code in JavaScript.

const toCamelCase = str => str.trim().replace(/[-_\s]+(.)?/g, (_, c) => c ? c.toUpperCase() : '');
toCamelCase('background-color'); // backgroundColor
toCamelCase('-webkit-scrollbar-thumb'); // WebkitScrollbarThumb
toCamelCase('_hello_world'); // HelloWorld
toCamelCase('hello_world'); // helloWorld
