got some information from an API and now want to pick "correct_answer" property from all of them and then make an array from correct_answer here is the API information :
apipresave=[
{question: "What does the "MP" stand for in MP3?",
correct_answer: "Moving Picture",
incorrect_answers: ["Music Player", "Multi Pass", "Micro Point"]},
{question: "What does GHz stand for?",
correct_answer: "Gigahertz",
incorrect_answers: ["Gigahotz", "Gigahetz", "Gigahatz"]},
{question: "In the programming language Java, which of these keywords would you put on a variable
to make sure it doesn't get modified?",
correct_answer: "Final",
incorrect_answers: ["Static", "Private", "Public"]},
]
btw I have already put this information on a const and have full access to them in code
I have tried to loop over them and use push to get them but it didn’t work
I put it below :
//puting all correct_answer into an array
function correct_answer_array_func (){
const correct_answer_array =[]
for(let i =0 ; i<4;i++){
correct_answer_array.push(apipresave[i].correct_answer)
return correct_answer_array
}
}
so how to obtain "correct_answer" from all the objects and put them in an array
the final result will be :
correct_answer_array =["Moving Picture","Gigahertz","Final"] // correct_answer values
>Solution :
You’re looking for the .map() Javascript Array method
Here is an example that should give you the array of values you are looking for.
const correct_answer_array = apipresave.map(item => item.correct_answer)
// ["Moving Picture","Gigahertz","Final"]
