Answer 1

Follow below step.

1. Link the mage/translate library:

   define (['jquery', 'mage/translate'], function ($) {...});

2. Use the $.mage.__('') function when adding a string:

   $.mage.__('<string>');

3. If your string contains a variable, to add a placeholder for this variable to the string stored in the dictionary, use the syntax similar to the following:

   $.mage.__('Hello %1').replace('%1', yourVariable);

I hope it helps!
