• ✓

  this[NavigationMixin.Navigate]({ type: 'standard__recordPage', attributes: { recordId: '001...', objectApiName: 'Account', actionName: 'view' } });

  Why this is correct

  This snippet correctly uses the NavigationMixin.Navigate method with a page reference object. The type 'standard__recordPage' is used to navigate to a record page, and the attributes specify the recordId, objectApiName, and actionName. This is the standard way to navigate to a record page in LWC using NavigationMixin.

• ✗

  NavigationMixin.Navigate(this, { type: 'standard__recordPage', attributes: { recordId: '001...', objectApiName: 'Account', actionName: 'view' } });

  Why it's wrong here

  This attempts to call Navigate as a static method on NavigationMixin, passing the component instance as the first argument. This is not how NavigationMixin works. The mixin is applied to the class, and the Navigate method is available on the instance. The correct usage is this[NavigationMixin.Navigate](pageReference).

• ✗

  this[NavigationMixin.Navigate](pageReference); where pageReference is defined as a string URL.

  Why it's wrong here

  The Navigate method expects a page reference object, not a string URL. While there is a type 'standard__webPage' that accepts a URL attribute, the page reference must be an object with a type and attributes. Passing a string directly will not work. The developer must construct a proper page reference object to navigate to a record page.

• ✗

  this.NavigationMixin.Navigate({ type: 'standard__recordPage', attributes: { recordId: '001...', objectApiName: 'Account', actionName: 'view' } });

  Why it's wrong here

  This syntax is incorrect because NavigationMixin is a mixin that must be applied to the component class, and its methods are accessed via the component instance using bracket notation. Using this.NavigationMixin.Navigate would not work because NavigationMixin is not a property on the instance; it is mixed into the class prototype. The correct access is via this[NavigationMixin.Navigate].
