Creating a JavaScript Object from two arrays
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.
Using ECMAScript2015:
const obj = newParamArr.reduce((obj, value, index) => {
obj[value] = paramArr[index];
return obj;
}, {});
(EDIT) Previously misunderstood the OP to want an array:
const arr = newParamArr.map((value, index) => ({[value]: paramArr[index]}))
I know that the question is already a year old, but here is a one-line solution:
Object.assign( ...newParamArr.map( (v, i) => ( {[v]: paramVal[i]} ) ) );
