Return string with array Javascript

Question

How can I insert both a string and an array to a return function and the array doesn't change??

function name(){
   let array = [1, 2, 3]
   return "Hello" + array  // I want Hello [ 1, 2, 3]
}

return array is equal to [ 1, 2, 3 ].

But return "Hello" + array is equal to Hello1,2,3.

What I want is Hello [ 1, 2, 3 ]

`'Hello' + JSON.stringify([1,2,3,])` – Jared Farrish Sep 28 '21 at 16:12 — Jared Farrish, Sep 28 '21 at 16:12

Like that?

function name(){
   let array = [1, 2, 3]
   return "Hello [ " + array.join(', ') + " ]";  // I want Hello [ 1, 2, 3]
}

As said in the comments thanks to Jared Farrish, you can simply use

'Hello' + JSON.stringify([1,2,3,])

For example

let array = [1,2,3];
console.log(JSON.stringify([ 1, 2, 3])) // [ 1, 2, 3]

You can check more use of the function by clicking JSON.stringify
