Handlebars and Javascript

Question

It's a good practice to include js file as partials in Handlebars? I mean, I need to use some data from nodejs in my jquery-based javascript, and to do this I load my js as partials in handlebars template and then use handlebars notation directly, this way:

$(document).ready(function() {
    var myVar = {{value_from_db}};
});

I know this it's not the correct way, I hope I've explained what I need.

In my case, I need to use MapBox coordinates inside the js, where the coordinates are get from database, this way:

var map = L.mapbox.map('map', 'mapbox.streets', {
        zoomControl: false,
        attributionControl: false
    }).setView([my_lat, my_lng], 3);

how may my_lat, my_lng rows exists in your database? – Atilla Ozgur Apr 10 '16 at 20:56 — Atilla Ozgur, Apr 10 '16 at 20:56

If your value_from_db is unique ok, otherwise "No. Do not do this."

When your js files are static, browser will cache them and do not download them again. But your js files are changing, how will you tell browser your file changed. Implementing this logic will be hard for you to do.

a.js , v1

$(document).ready(function() {
    var myVar = 20;
});

a.js , v2

$(document).ready(function() {
    var myVar = 30;
});
