How do vue custom components respond to events in the parent component?

problem description

I customized a cont component, then referenced it in another component A, and placed some content in the cont component. How do I define events? For example, click, my way of writing is not supported, what should the correct way of writing look like? Is there a boss who loses a portal? thank you

methods: {
        click: () => {
            console.log("")
        }
    },

/ / cont components
< template >

<div class="content">
    <slot></slot>
</div>

< / template >

officials say that methods cannot use the arrow function
and then if you want to trigger it in the component, either $emit, or this.$props.click ()
