Multiple variables declaration in ejs

Question

I am trying to declare and assign a default value to multiple variables. But the value is only getting assigned to last variable

<% var scale_text,scale_image = 'free_transform'; %>

This print empty:

<%- scale_text %>

This prints free_transform

<%- scale_image %>

What am i missing?

Separate the variables with = to set them to the same default value.

<% var scale_text, scale_image; %>
<% scale_text = scale_image = 'free_transform'; %>

Why is it better? – Luis Antonio Canettoli Ordoñez Sep 15 '22 at 14:33
@LuisAntonioCanettoliOrdoñez It's better because it won't declare scale_image as a global in quirks mode and won't result in a `ReferenceError` in strict mode. (However, I'm not sure how all that works in EJS.) – Trott Sep 16 '22 at 02:40

What your writing will declare scale_text as an empty variable.

To work the way you want it to you need to do the following

<% var scale_text = scale_image = 'free_transform'; %>

However this is probably preferable

<% var scale_text, scale_image; %> <% scale_text = scale_image = 'free_transform'; %>
