How to filter an array of objects nested array - filter

Question

Im implementing a new feature into my project for when a user begins to search for a tag input, which is a value stored inside of a nested array. With the code that I have currently written, if the whole tag keyword has been typed out, we get back the corresponding user data. Im trying to get this work on every keystroke. I tried to use 'match()' but no luck. Any tips are greatly appreciated.
.... I figured it out
const filterDataByTag = (value) => {
let tagFilter;
let valueLowercase = value.toLowerCase();
if (initialData.data) {
tagFilter = initialData.data.filter((item) => {
item.tag.map((tag) => tag.toLowerCase());
return item.tag.toString().match(valueLowercase);
});
setFilterData(tagFilter);
}
};
