I would like to get 'experiments[0].name' but I have error that name is not defined. How to get this property?
let experiments = [ {name: "C200929R01_SizeMarker", file: experiments[0].name + ".xrrx"} ];
Until that closing ] experiments indeed won't be defined.
If your just trying to save typing the name in twice, you could retructure like ->
const name = "C200929R01_SizeMarker";
let experiments = [ {name, file: name + ".xrrx"} ];
console.log(experiments);let experiments = [ {name: "C200929R01_SizeMarker", file: experiments[0].name + ".xrrx"} ];
When you are asigning file: experiments[0].name, experiments[0] is not defined yet, so you have different options:
let experiments = [{name: "C200929R01_SizeMarker"}];
experiments[0].file = experiments[0].name + ".xrrx";
Or using the option described in the previous answer
