no-extra-mut-helper-argument

✅ The extends: 'recommended' property in a configuration file enables this rule.

A common mistake when using the Ember handlebars template mut(attr) helper is to pass an extra value parameter to it when only attr should be passed. Instead, the value should be passed outside of mut.

Examples

This rule forbids the following:

{{my-component click=(action (mut isClicked true))}}

This rule allows the following:

{{my-component click=(action (mut isClicked) true)}}
