You need to add the item primary key in the like_function call:

<button onclick="like_function({{ posts.pk }})" id = "like" class="btn btn-link"><i class="fa fa-heart"></i> </button>

then you define the like_function as:

function like_function(id) {
    fetch(`index/${id}/like`)
    .then(response => response.json())
    .then(result => {
        if(result.is_like){
            document.querySelector('#like').innerHTML = "Like";
        }
        else{
            document.querySelector('#like').innerHTML = "Unlike";
        }
    })
}
