Merging JQuery arrays and converting to JSON format

Question

I have a set of JQuery arrays that I need to join into a single array, jsonify and pass to the python script in the back end.

my_jq.js:

var a = ['one','two'];
var b = ['three','four'];
var c = ['five'];
var d = ['six','seven','eight'];

I tried this, but it does not generate an array:

var e = $.merge(a,b,c,d)
var json_array = JSON.stringify(e)

What am I doing wrong?

var a = ['one','two'];
var b = ['three','four'];
var c = ['five'];
var d = ['six','seven','eight']; 

var myJsonString = JSON.stringify(a.concat(b,c,d));
console.log( myJsonString );

.as-console-wrapper{top:0}

The $.merge jQuery function only takes two parameters. What you have is working but the values in c and d will be omitted.

You can use concat: [].concat(a,b,c,d)

or in ES6 with the spread syntax = var e = [...a, ...b, ...c, ...d]

It works - I get an Array object in the Inspect > Console. However, when I am calling array e, it comes back empty
