I have an array of objects like this:
const arr = [
{
question_Number: 205,
question_Text: "Enter Engine Number",
},
{
question_Number: 497,
question_Text: "Whether imported?",
},
{
question_Number: 547,
question_Text: "Whether goods are new?",
},
{
question_Number: 206,
question_Text: "Select Vehicle Condition",
},
];
and I want to transform it into an object of key/value pairs as this:
const result = {
205: {
type: "string",
title: "Enter Engine Number",
},
497: {
type: "string",
title: "Whether imported?",
},
547: {
type: "string",
title: "Whether imported goods are new?",
},
206: {
type: "string",
title: "Select Vehicle Condition",
},
};
How can I achieve this result using plain javascript or even lodash?
Thanks.
You could map entries with new objects.
const
data = [{ question_Number: 205, question_Text: "Enter Engine Number" }, { question_Number: 497, question_Text: "Whether imported?" }, { question_Number: 547, question_Text: "Whether goods are new?" }, { question_Number: 206, question_Text: "Select Vehicle Condition" }],
result = Object.fromEntries(data.map(({
question_Number,
question_Text: title
}) => [question_Number, { type: 'string', title }]));
console.log(result);.as-console-wrapper { max-height: 100% !important; top: 0; }You can do this with built in things but I think this would be more understandable to see what is going on, something real quick:
const input = [
{
question_Number: 205,
question_Text: "Enter Engine Number",
},
{
question_Number: 497,
question_Text: "Whether imported?",
},
{
question_Number: 547,
question_Text: "Whether goods are new?",
},
{
question_Number: 206,
question_Text: "Select Vehicle Condition",
}
]
const transformArray = (arr) => {
let result = {}
for (let i = 0; i < arr.length; i++) {
result[arr[i].question_Number] = { type: typeof arr[i].question_Text, title: arr[i].question_Text }
}
return result
}
console.log(transformArray(input))
