how to add two arrays in one array

Question

I am trying to merge two arrays data in one array format but getting empty array how to solve this please help me out this.

array1= ["hjghh", "hjghhs", "hjghhsjj"]
    0:
    0:"hjghh" 
    1:"hjghhs"
    2:"hjghhsjj"
    array2=["data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"]
    0:
    0: "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"
    1: "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"
    2: "data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"

in array3 I want to display like this

    0:
    0:["hjghh","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"]
    1:["hjghhs","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"]
    2:["hjghhsjj","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"]

this.barcodetextone is 1st array
this.ShowImgoriginal is 2nd array

let arr3:any=[];
this.barcodetextone.forEach((i) => {
    arr3.push(Object.assign({}, this.ShowImgoriginal[i]));
});

console.log(arr3);

Why use Object.assign? Just use arr3 = this.barcodetextone.map((elem, i) => [elem, this.ShowImgoriginal[i]]);. — Sebastian Simon

Use the index in the first array to get the values for the second array and push an array with both:

let array1 = ["hjghh", "hjghhs", "hjghhsjj"];
let array2 = ["data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD","data:image/jpeg;base64,/9j/4AAQSkZJRgABAQAAAQABAAD"];
let result = [];

array1.forEach((i, index) => {
    result.push([i, array2[index]])
})

console.log(result);

-1

    let arr1 = ['a','b','c']
    let arr2 = [1,3,51,51,2,1,0]
    let arr3 = [...arr1,...arr2]
    let zib = {}
    arr3.forEach((elem,index)=> {
        zib[index] = elem
    })

is this what you meant ?
