@name Missing let keyword in an *ngFor expression

@description

This diagnostic is emitted when an expression used in *ngFor is missing the let keyword.

import {Component} from '@angular/core';

@Component({ // The let keyword is missing in the *ngFor expression. template: <div *ngFor="item of items">{{ item }}</div>, // … }) class MyComponent { items = [1, 2, 3]; }

How to resolve the problem

Add the missing let keyword.

import {Component} from '@angular/core';

@Component({ // The let keyword is now present in the *ngFor expression, // no diagnostic messages are emitted in this case. template: <div *ngFor="let item of items">{{ item }}</div>, // … }) class MyComponent { items = [1, 2, 3]; }
