objectFromPairs

Creates an object from the given key-value pairs.

Use Array.reduce() to create and combine key-value pairs.

const objectFromPairs = arr => arr.reduce((a, v) => ((a[v[0]] = v[1]), a), {});
+

objectFromPairs

Creates an object from the given key-value pairs.

Use Array.reduce() to create and combine key-value pairs.

const objectFromPairs = arr => arr.reduce((a, [key, val]) => ((a[key] = val), a), {});
 
objectFromPairs([['a', 1], ['b', 2]]); // {a: 1, b: 2}

objectToPairs

Creates an array of key-value pair arrays from an object.

Use Object.keys() and Array.map() to iterate over the object's keys and produce an array with key-value pairs.

const objectToPairs = obj => Object.keys(obj).map(k => [k, obj[k]]);
 
objectToPairs({ a: 1, b: 2 }); // [['a',1],['b',2]]
