I developed an application using IONIC-2 Beta version and I am interested in incorporating a for-each loop. Can anyone advise if it is possible to use for each in Angular-V2?
Thank you.

Thank you.
To begin in the Component, start by defining the array you wish to display:
import { Component } from "@angular/core";
@Component({
templateUrl:"home.html"
})
export class HomePage {
dataToShow: [];
constructor() {
this.dataToShow = [
{
"text": "item 1",
"value": 1
},
{
"text": "item 2",
"value": 2
},
{
"text": "item 3",
"value": 3
},
{
"text": "item 4",
"value": 4
},
{
"text": "item 5",
"value": 5
},
];
}
}
If you want to modify the values within the code, you can do so like this:
// Iterate over the array in the code
for(let item of this.dataToShow) {
item.value = item.value + 5;
}
Then, in your View, you can display them as follows:
<ion-content class="has-header">
<ion-list *ngFor="let item of dataToShow; let i = index" no-lines>
<ion-item>Index: {{ i }} - Text: {{ item.text }} - Value: {{ item.value }}</ion-item>
</ion-list>
</ion-content>
Note the section *ngFor="let item of dataToShow" where:
dataToShow is the array we defined in the Componentlet item of ... creates a new variable called item, representing each element of the dataToShow array.item variable and interpolation like {{ item.propertyName }}.Struggling with setting up a lambda function in IntelliJ WebStorm using node 16, Typescript, and modules instead of plain Javascript with commonJS.
