You need to have a conditional class like this, based on whether the current item is part of secondArr or not.
{firstArray.map((item, index) => (
<label
className={`btn btn-secondary ${secondArr.includes(item) ? 'different-bg-class' : ''}`}
key={index}
>
<input type="checkbox" onChange={this.handleAddItem} value={item} /> {item}
</label>
))}
