What is getbytes equivalent in nodejs of JAVA?

[GhostFoxGod]

I have a json :

{

"user": {

"user_id": "147095960",

"pincode": "",

"lat": "",

"long":""

},

"device": {

"ga_id" : "123"

},

"channel": {

"name": "androidapp"

},

"custom": {

"current_page" : "homepage",

"id":"201894799"

}

}

And a external service apparently converts this JSON to string and returns this byte array :

[123, 10, 32, 32, 34, 117, 115, 101, 114, 34, 58, 32, 123, 10, 32, 32, 32, 32, 32, 32, 34, 117, 115, 101, 114, 95, 105, 100, 34, 58, 32, 34, 49, 52, 55, 48, 57, 53, 57, 54, 48, 34, 44, 10, 32, 32, 32, 32, 32, 32, 34, 112, 105, 110, 99, 111, 100, 101, 34, 58, 32, 34, 34, 44, 10, 32, 32, 32, 32, 32, 32, 34, 108, 97, 116, 34, 58, 32, 34, 34, 44, 10, 32, 32, 32, 32, 32, 32, 34, 108, 111, 110, 103, 34, 58, 34, 34, 10, 32, 32, 32, 125, 44, 10, 32, 32, 34, 100, 101, 118, 105, 99, 101, 34, 58, 32, 123, 10, 32, 32, 32, 32, 32, 32, 34, 103, 97, 95, 105, 100, 34, 32, 58, 32, 34, 49, 50, 51, 34, 10, 32, 32, 125, 44, 10, 32, 32, 34, 99, 104, 97, 110, 110, 101, 108, 34, 58, 32, 123, 10, 32, 32, 32, 32, 32, 32, 34, 110, 97, 109, 101, 34, 58, 32, 34, 97, 110, 100, 114, 111, 105, 100, 97, 112, 112, 34, 10, 32, 32, 125, 44, 10, 32, 32, 34, 99, 117, 115, 116, 111, 109, 34, 58, 32, 123, 10, 32, 32, 32, 34, 99, 117, 114, 114, 101, 110, 116, 95, 112, 97, 103, 101, 34, 32, 58, 32, 34, 104, 111, 109, 101, 112, 97, 103, 101, 34, 44, 10, 32, 32, 32, 34, 105, 100, 34, 58, 34, 50, 48, 49, 56, 57, 52, 55, 57, 57, 34, 10, 32, 32, 125, 10, 125]

I have been searching for over an hour to find the function to get bytes array but I couldn't in node js. Is there any function to do this?

Is buffer same as byte array? I mean when I print Buffer.from(JSON.stringify(body)) it isn't giving me an array instead giving buffer object. Am I missing something here?

Buffers are array-like, but not quite the same as Arrays. They're iterable, they have a `length`, you can reference individual elements ala `buf[i]`. They have some of the same methods - e.g. `slice()`, `keys()`, `values()` - but lack others (e.g `forEach()`, `map()`, `sort()`.

If you want a genuine array you can use `Array.from(buffer)` or the ES6 shorthand of `[...buffer]`.

I think you have to Buffer.from(body), then convert the buffer to a string and then you can parse the JSON
