How can I efficiently utilize Lodash while iterating through an array to extract and assign relevant values?
I have an unfiltered array which contains ID and name[x].text elements. Some objects in the array may not have French text available, in which case I want to default to English text.
const response = {
"data": {
"Animals": [
{
"id": "1",
"name": [
{
"language": "en-US",
"text": "Horse"
}
]
},
...
]
}
}
console.log(response.data.Animals.map(animal => animal.name[0].text)); // Accesses only English text, but I need to handle cases where French text is present.
In order to achieve a more accurate result that includes both French and English text with some improvements, follow these steps:
Retrieve values based on keys ("en-US" and "fr-CA") to ensure correct data selection.
While populating a table using mapping, avoid creating a new array as it may lead to index loss if text is missing, defaulting to English text instead.
For advanced usage of Lodash to set values (either in English or French), you can implement the following:
arr.map((obj) => { const id = obj.id; const englishtext = _.get(obj, 'name[0].text', 'N/A'); const frenchtext = _.get(obj, 'name[1].text', englishtext); return { id, englishtext, frenchtext };}
UPDATE: I apologize for any confusion caused by my initial question. To clarify, I seek an expected output resembling the following format when mapping the 'response' variable:
EXPECTED OUTPUT:
[
{
id: 1,
engname: Horse,
frenchname: Horse (fallback to English),
},
...
{
id:3,
engname:Cat,
frenchname: Un Chat, (French option available)
}
...
and so forth..
