Find matched string in an object that contains mutiple arrays

I have an object that contains multiple arrays of strings, like

const object = {
    "arrayA": [
        "A1",
        "A2"
    ]
    "arrayB": [
        "B1",
        "B2"
    ]
    ...
}

How can I use Javascript function or lodash to find if a given string exists in the object? Thanks

Using Object#values, get the list of arrays
Using Array#some, iterate over this list to check if any array has the string using Array#includes

const checkForString = (obj = {}, str) =>
  Object.values(obj).some(arr => arr.includes(str));

const object = { "arrayA": [ "A1", "A2" ], "arrayB": [ "B1", "B2" ] };

console.log( checkForString(object, "A1") );
console.log( checkForString(object, "B1") );
console.log( checkForString(object, "C1") );
