How do i make switch and if statement in one function

function texas(val) {
    var answer = "";
    switch(val) {
        case 1:
        case 2:
        case 3:
            var answer = "low";
        case 4:
        case 5:
        case 6:
            var answer = "medium";
            break;
    } else if(val =>  7) {
        var answer = "Huge"
    }
    return answer;
}

it says error Declaration or statement expected. ts(1128) [13, 7] and it poits at the else if statement
