Example:

\n
capitalize("my first sentence")\n// My First Sentence\n\ncapitalize("hemanta sundaray")\n// Hemanta Sundaray

const capitalize = str => {\n  const strArray = str.split(" ")\n\n  const strCapitalized = strArray.map(element => {\n    const firstChar = element[0].toUpperCase()\n    const remainingChars = element.slice(1)\n    return `${firstChar}${remainingChars}`\n  })\n\n  return strCapitalized.join(" ")\n}\n\nconsole.log(capitalize("React query is cool"))\n// React Query Is Cool
