You can use the find method:

items.find((item) => this.mainItem.includes(item)) || ""

You can use the boolean:

items.findIndex((el) => this.mainItem.includes(el)) !== -1

We use the new findIndex method and check if main tiem includes the element. If not, then the function returns -1

You can use the .filter() function:

items.filter((item) => this.mainItem.includes(item))// will return Array [ "hat" ]
