Why is my product variant id script not working properly?

Hello,

I want to get the product variant id to add some script to it.

For example: {{- product.selected_or_first_available_variant.id -}} outputs 44243511738635

When I try this:

{{- product.selected_or_first_available_variant.id -}}

{%- if product.selected_or_first_available_variant.id == ‘44243511738635’ -%}

test

{%- endif -%}

it gives:

44243511738635

instead of

44243511738635

test

Why is this line {%- if product.selected_or_first_available_variant.id == ‘44243511738635’ -%} not working?
