I'm trying to use a variable to access a field in my json file, how do I do something like this? js:
let file = require('./file.json')
let someVar = 'firstField'
console.log(file.firstObject.{someVar})
json:
{
"firstObject": {
"firstField":"firstValue",
"secondField":"secondValue",
"thirdField":"thirdValue",
},
"otherObject": {
"otherField":"otherValue"
}
}
desired outcome :
'firstValue'
object[str] is what you are looking for.
Your code should look like this:
let file = require('./file.json')
let someVar = 'firstField'
console.log(file.firstObject[someVar])
