JavaScript: Get the symmetric difference between two given arrays
JavaScript fundamental (ES6 Syntax): Exercise-134 with Solution
Write a JavaScript program to get the symmetric difference between two given arrays.
- Create a new Set() from each array to get the unique values of each one.
- Use Array.prototype.filter() on each of them to only keep values not contained in the other.
Sample Solution:
JavaScript Code:
//#Source https://bit.ly/2neWfJ2
const symmetricDifference = (a, b) => {
const sA = new Set(a),
sB = new Set(b);
return [...a.filter(x => !sB.has(x)), ...b.filter(x => !sA.has(x))];
};
console.log(symmetricDifference([1, 2, 3], [1, 2, 4]));
Sample Output:
[3,4]

JavaScript: Tips of the Day
Chunks an array into n smaller arrays
Example:
const tips_chunkIntoN = (arr, n) => { const size = Math.ceil(arr.length / n); return Array.from({ length: n }, (v, i) => arr.slice(i * size, i * size + size) ); } console.log(tips_chunkIntoN([1, 2, 3, 4, 5, 6, 7,8], 4));
Output:
[[1,2],[3,4],[5,6],[7,8]]
