Below please find the JSON response. What I need is to get all "descriptions" returned in that JSON response object. To loop through and get the descriptions I need a way to get the index of, in my case, of the "textAnnotations".
In the following JSON 4 "textAnnotations" have been returned, How do I get this 4?
What I need is to get:
payload.responses[0].textAnnotations[0].description
payload.responses[0].textAnnotations[1].description
payload.responses[0].textAnnotations[2].description
payload.responses[0].textAnnotations[3].description

CodePudding user response：
you can do something like this to extract the descriptions
const getDescriptions = data =>
data.flatMap(d => d.textAnnotations?
d.textAnnotations.map(t => t.description):
[]
)
const data = {

You can use map to loop through the array as follows:
payload.responses[0].textAnnotations.map((textAnn, index) => {
return textAnn.description
})
