What is the best way to display two arrays next to each other in an Angular template?

bolded text

I am struggling to display two arrays side by side in an angular template. I attempted to use ngFor inside a div and span but the result was not as expected. A=[1,2,3,4] B=[A,B,C,D]

Current Outcome using ngFor with div and span :

Using Div :

1

2

3

4

A

B

C

D

Using Span: 1 2 3 4 A B C D

Expected output:

1 A

2 B

3 C

4 D

The desired output should look like the above, seeking assistance for achieving this.

Answer №1

Simply utilize the keyword "index" when working with the second array

<div *ngFor="let item of a; let i=index>
{{item}}{{b[i]}}
</div> 

Answer №2

If you're looking to level up your coding skills, try creating a 2D array by utilizing the .map() method and then implementing the resulting array with the help of *ngFor:

JavaScript:

let numbers = [1, 2, 3, 4];
let letters = ['A', 'B', 'C', 'D'];
let combinedArray = numbers.map((num, index) => [num, letters[index]]);

HTML:

<div *ngFor="let element in combinedArray">
    {{element[0]}} {{element[1]}}
</div>

Answer №3

Utilizing *ngFor in Angular allows for easy access to the index of an array, along with other useful exported values. To learn more about these capabilities, please consult the Angular Documentation.

Recommended Solution:

<div *ngFor="let value of firstArray; let i = index">{{value}} {{secondArray[i]}}</div>
