Javascript Array Of Object Value Into Multidimensional Array

I am in process of learning expressJS with NodeJS. I am trying to insert multiple rows into mySQL table. Since the bulk insert query requires data like [['a',1], ['b',2], ['c',3]]

Solution 1:

You could pass Object.values as parameter to map like this:

const input = [
 {
    "productID" : 1,
    "stock": -3
 },
 {
    "productID" : 1,
    "stock": 5
 }
]

const output = input.map(Object.values)
console.log(output)
