ES6 syntax error: 'operator is only available in ES6 (use 'esversion: 6')'

[lala_guliyeva]

Hello,

My platform version is ThingWorx 8.5.4-b222

In service I try to use spread operator:

const result = [...arr1, ...arr2];

 But I receive error:

'spread operator' is only avaiable in ES6 (use 'esversion: 6')

How can I fix it?

Thanks in advance.

Hi,

Could you provide a code example to reproduce it?

Thanks,

hi,

yes, sure:

const arr1 = [0, 1, 2];
const arr2 = [3, 4, 5];
let result = [...arr1, ...arr2];

Hi,

I don't think spread operator is supported, Thingworx 8.5.x is using Rhino Javascript Engine 1.7.11. 

See here a support table:

Hope it helps,
