javascript keyvalue object

Javascript convert key value string to Object

Let the following "key value string":

"maxRU=5000;database=rktmb_credit;counting=databaseLevel"

I want that string to be converted to Objet or JSON:

{ maxRU: '5000', database: 'rktmb_credit', counting: 'databaseLevel' }

Use Object.fromEntries()

A built-in tool that is Use Object.fromEntries() where it states that:

const arr = [ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];
const obj = Object.fromEntries(arr);
console.log(obj); // { 0: "a", 1: "b", 2: "c" }

So, the target is to get something like

[ ['0', 'a'], ['1', 'b'], ['2', 'c'] ];

From

"maxRU=5000;database=rktmb_credit;counting=databaseLevel"

In order to achieve that, we need a small utility:

const parseDescription = function (d)  {
    var a1 = d.split(";");
    var r = a1.map(f => {return f.split("=");});
    return r;
}

And this is how it executes in a Node REPL:

mihamina@a-onp ~]$ /home/mihamina/Apps/node/bin/node 
Welcome to Node.js v16.17.0.
Type ".help" for more information.
> const parseDescription = function (d)  {
...     var a1 = d.split(";");
...     var r = a1.map(f => {return f.split("=");});
...     return r;
... }
undefined
> result=Object.fromEntries(parseDescription("maxRU=5000;database=rktmb_credit;counting=databaseLevel"));
{ maxRU: '5000', database: 'rktmb_credit', counting: 'databaseLevel' }

We got what we want.
