JavaScript: Remove the key-value pairs corresponding to the given keys from an object
JavaScript fundamental (ES6 Syntax): Exercise-39 with Solution
Write a JavaScript program to remove the key-value pairs corresponding to the given keys from an object.
- Use Object.keys(), Array.prototype.filter() and Array.prototype.includes() to remove the provided keys.
- Use Array.prototype.reduce() to convert the filtered keys back to an object with the corresponding key-value pairs.
Sample Solution:
JavaScript Code:
//#Source https://bit.ly/2neWfJ2
const omit = (obj, arr) =>
Object.keys(obj)
.filter(k => !arr.includes(k))
.reduce((acc, key) => ((acc[key] = obj[key]), acc), {});
console.log(omit({ a: 1, b: '2', c: 3 }, ['b']));
console.log(omit({ a: 1, b: 2, c: 3 }, ['c']));
Sample Output:
{"a":1,"c":3} {"a":1,"b":2}
