How about
if([var1, var2, var3, var4, var5, var6, var7, var8].filter((x) => x === '').length) {
alert("null value");
} else {
alert("good");
}

If any of the variables is empty, then it alerts the null value otherwise everything is good to go.
if ([var1, var2, var3, var4, var5, var6, var7, var8].some(el => el == "")) {
alert("null value");
} else {
alert("good");
}
