Benchmark: Set difference comparison

HTML Preparation code:

<!--your preparation HTML code goes here-->

Script Preparation code:

/*your preparation JavaScript code goes here
To execute async code during the script preparation, wrap it as function globalMeasureThatScriptPrepareFunction, example:*/
const arrayA = ["A","B","C","D","E","F","G","H","I","J","K"];
const arrayB = ["C","F","J"];

Tests:

Symmetrical set difference
/*When writing async/deferred tests, use `deferred.resolve()` to mark test as done*/ const setA = new Set(arrayA); const setB = new Set(arrayB); // Elements in A not in B const diffA = Array.from(setA).filter(x => !setB.has(x)); // Elements in B not in A const diffB = Array.from(setB).filter(x => !setA.has(x)); const symmetricDifference = [...diffA, ...diffB]; console.log(symmetricDifference);
Set difference using filter
const setA = new Set(arrayA); const setB = new Set(arrayB); // Elements in A not in B const diffA = Array.from(setA).filter(x => !setB.has(x)); console.log(diffA);
Array loop
// Elements in array1 not in array2 const difference1 = arrayA.filter(x => !arrayB.includes(x)); console.log(difference1);
