Let's imagine we have an object as follows:
data = {
Apple: 5,
Banana: 8,
Orange: 12,
Mango: 3
}
If I wanted to retrieve the values corresponding to an array of keys using vanilla JavaScript or jQuery, how could I accomplish this? For example:
var keys = ["Banana", "Mango"]
Object.values(data)[keys]
The desired output would be an array containing the values [8, 3]
To achieve this, you can utilize the map function
const info = {
apple: 5,
banana: 2,
orange: 8,
pear: 3
}
let selection = ["apple", "pear"]
const outcome = selection.map(item => info[item])
