SyntaxError: expected expression, got '&' (Django)

I have an analytic dashboard with Django as a backend. After analyzing data in Python I'm sending a dictionary with name and salience.

var things_mentioned = {{entity.name}};
var things_salience = {{entity.salience}};

which produces an error: SyntaxError: expected expression, got '&'

Below code does not produce any error and works perfectly:

var things_mentioned = ['noodles', 'food', 'Chinese', 'flavor', 'umami flavor'];
var things_salience = {{entity.salience}};

when I try to view {{entity.name}} value in plain HTML page it exactly displays this

['noodles', 'food', 'Chinese', 'flavor', 'umami flavor'].

Also, there is not a single '&' in my entire program.

It will try to HTML-escape the string. You can use JavaScript escaping. The safest way is probably to use the |json_script template filter [Django-do]. You can thus use this as:

{{ entity.name|json_script:"things_mentioned" }}
var things_mentioned = JSON.parse(document.getElementById('things_mentioned').textContent);
