Parameter 'item' implicitly has an 'any' type

I'm working on the UI Kitten component called Autocomplete.

I've followed their Documentation, but since it's in React and not typescript, and I'm quite new on typescript, I always get the same error of "Parameter 'item' implicitly has an 'any' type."

The code i have is the following:

  export const HSCodes = [    { description: 'A RANDOM NAME', HSCode: 'A RANDOM CODE' },    ... many more  ];  function filterItem(item, query: string) {    if (item.description.includes(query.toUpperCase())) {      return item.description.includes(query.toUpperCase());    } else if (item.HSCode.includes(query.toUpperCase())) {      return item.HSCode.includes(query.toUpperCase());    }  }  const onSelectHS = (index: number) => {    setHsCode(HSCodes[index].HSCode);  };  const onChangeTextHS = (query: string) => {    setHsCode(query);    setDataHS(HSCodes.filter((item: object) => filterItem(item, query)));  };  const renderOptionHS = (item, index: number) => (<AutocompleteItem key={index} title={item.description +''+ item.HSCode} />  );... things not important<Autocomplete    placeholder={t('Enter DUA Number')       value={hsCode}    style={styles.autoComplete}    onSelect={onSelectHS}    onChangeText={onChangeTextHS}    onBlur={saveHsCode}>    {dataHS.map(renderOptionHS)}</Autocomplete>

I'm struggling because if I declare item: object, it all breaks down, what it actually says when I declare item as object for example in the filterItem

Property 'description' does not exist on type 'object'.
