Creating a JavaScript Object from two arrays

Question

I have two arrays: newParamArr[i] and paramVal[i].

Example values in the newParamArr[i] array: [\"Name\", \"Age\", \"Ema

Answer 1

var keys = ['foo', 'bar', 'baz'];
var values = [11, 22, 33]

var result = {};
keys.forEach((key, i) => result[key] = values[i]);
console.log(result);

Alternatively, you can use Object.assign

result = Object.assign(...keys.map((k, i) => ({[k]: values[i]})))

or the object spread syntax (ES2018):

result = keys.reduce((o, k, i) => ({...o, [k]: values[i]}), {})

or Object.fromEntries (ES2019):

Object.fromEntries(keys.map((_, i) => [keys[i], values[i]]))

In case you're using lodash, there's _.zipObject exactly for this type of thing.
