I can achieve this using the for loop but I cant figure out how to use forEach to do the same.
for example:
var input = [['make', 'Ford'], ['model', 'Mustang'], ['year', 1964]];
calling the function should result in:
{
make : 'Ford',
model : 'Mustang',
year : 1964
}
We can achieve this using forEach and Array destructuring
var input = [
["make", "Ford"],
["model", "Mustang"],
["year", 1964],
];
const result = {};
input.forEach(([prop, value]) => {
result[prop] = value;
});
/*--------- OR --(withour array destructuring)-------------
input.forEach(internalArr => {
result[internalArr[0]] = internalArr[1];
});
*/
console.log(result);You can also achieve this using Array.prototype.reduce. Array.prototype.reduce is the right tool to do this job.
var input = [
["make", "Ford"],
["model", "Mustang"],
["year", 1964],
];
const result = input.reduce((acc, curr) => {
const [prop, value] = curr;
acc[prop] = value;
return acc;
}, {});
console.log(result);
reduce among others solutions. This question asks for answers using forEach.
Array.prototype.reduce is not the right tool. It doesn't differ from other loop construct, really.Array.prototype.reduce is not the right tool. May be there is something that I don't know. So that I can learn something new from you. ☺☺☺You could take a closure for the target object and iterate the array with the returned function from convert.
const
convert = target => ([key, value]) => target[key] = value,
input = [['make', 'Ford'], ['model', 'Mustang'], ['year', 1964]],
output = {};
input.forEach(convert(output));
console.log(output);
forEach?reduce) DO NOT ANSWER THIS QUESTION. This question asks about usingforEach.Object.fromEntries()with the array as parameter.
