input: Write a function to convert a list of strings to camelCase and return a new list with the converted strings. The function should take a list of strings as input and return a single concatenated string in camelCase format. 
  def convertToCamelCase(list):
      camelCaseList = []
      for i, string in enumerate(list):
          if i == 0:
              camelCaseList.append(string.lower())
          else:
              camelCaseList.append(string.capitalize())
      return ''.join(camelCaseList)
  
  assert convertToCamelCase(['this', 'is', 'an', 'example'])=='thisIsAnExample'
  assert convertToCamelCase(['camel', 'case', 'format'])=='camelCaseFormat'
  assert convertToCamelCase(['hello', 'world'])=='helloWorld'
  assert convertToCamelCase(['capitalized', 'strings', 'needed'])=='capitalizedStringsNeeded'
