在JavaScript中将camelToCase转换为snake_case

编写一个函数，将单个camelCase格式的字符串转换为snake_case格式的字符串。

解决方案

// A function camelToCase that takes a string (text) as the parameter.
function camelToCase(text) {

  // Transform each uppercase letter (character) based on its position.
  function upperToUnderScoreLower(character, position) {

    // If the letter isn't the first character, add an underscore and convert it to lowercase.
    return (position > 0 && "_") + match.toLowerCase();
  }

  // Replace all uppercase letters in (text) by calling the upperToUnderScoreLower function.
  return text.replace(/[A-Z]/g, upperToUnderScoreLower);
}

console.log(camelToCase("camelToCase"));

结果

> camel_to_case
