[
{
"item": "1",
"values": [{"name": "A"}]
},
{
"item": "2",
"values": [{"name": "B"}]
},
{
"item": "3",
"values": [{"name": "A"}]
}
]
The desired outcome is to extract ["A", "B"] based on the values in the name field.
How would you approach this task using Javascript? Your insights are appreciated.
At first glance, there seems to be a syntax error in the way your nested array is defined.
"values": ["name": "A"] // this is not valid javascript
It appears that you may have intended for it to look more like this:
x=[
{
"item": "1",
"values": {"name": "A"}
},
{
"item": "2",
"values": {"name": "B"}
},
{
"item": "3",
"values": {"name": "A"}
}
]
As for your main question - I recommend using underscore JS or the Lodash library, particularly their map functions. Assuming you are working with the object 'x' as defined above and using underscore JS...
.map(x, function(y){return y.values.name})
["A", "B", "A"]
Hopefully this information proves helpful to you.
