I'm making a get request similar to this:

axios.get('https://example.org/getJobs', { params: { salaries, ... } }); // ... represents more params

where salaries is an array of arrays, or ranges, that I use to filter the jobs returned. I can access it fine on req.query.salaries, but it arrives on the server in the following format:

[ '["0","20000"]', '["20000","30000"]', '["30000","40000"]' ]

I'm just wondering what the best way to parse this is?

*Edit: Just to be clear, the array is originally sent in this format: [['0', '20000'], ['20000', '30000'], ['30000', '40000']]

salaries logged just before calling axios.get():

(5) [Array(2), Array(2), Array(2), Array(2), Array(2)]
0: (2) ['0', '20000']
1: (2) ['20000', '30000']
2: (2) ['30000', '40000']
3: (2) ['40000', '50000']
4: (2) ['50000', '60000']
length: 5
[[Prototype]]: Array(0)

send salaries as an array, is no need to send as array of json strings – Lawrence Cherone Dec 01 '21 at 22:04
Thanks Lawrence. How would I do that with an axios get request though? (I think it's axios that's serialising the array) – NickW Dec 01 '21 at 22:07
can you show the code which defines salaries? – Lawrence Cherone Dec 01 '21 at 22:08
Not easily, but I'm logging the salaries array just before the axios request, I'll add the log to the OP – NickW Dec 01 '21 at 22:12

something like `const onServerData = req.query.salaries.map(s=>JSON.parse(s))` – Babak Karimi Asl Dec 01 '21 at 22:21
Lol. I swear blind I tried that @BabakKarimiAsl, it was even in one of my edits. I must have made a mistake somewhere. Thanks both of you – NickW Dec 01 '21 at 22:30
