What is the role of the logical operator in the conditional statement {{#if}} in handlebars.js?

edit

The logical operator in the conditional statement {{#if}} in handlebars.js is used to evaluate a boolean expression and determine whether a certain block of code should be rendered or not. It allows for conditional logic to be implemented in templates, based on a boolean value or a comparison of two values. The logical operators commonly used in handlebars.js include && (and), || (or), and ! (not). By using these operators, developers can create more sophisticated templates that can handle complex conditional scenarios.
