I'm getting a output data from a device as series of array. This array comes 5 times each time carrying a 64 item in it while swiping a card into the device. I want to concat these array. Below is the final array I got. I know array.concat(array2) should work but due to some reason it is not. Can anybody tell me what am I doing wrong here or any suggestion

Merge Array with Push:
const array1 = [2, 7, 4];
const array2 = [3, 5,9];
array1.push(...array2);
console.log(array1)Using Concat and Spread operator:
const array1 = [1,2];
const array2 = [3,4];
// Method 1: Concat
const combined1 = [].concat(array1, array2);
// Method 2: Spread
const combined2 = [...array1, ...array2];
console.log(combined1);
console.log(combined2);この記事はインターネットから収集されたものであり、転載の際にはソースを示してください。
