To provide an answer, I'll need to parse the input data and perform some calculations based on it.
The input contains three main parts:
9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16
2. A string describing the HTML preparation code:
Html Preparation Code: null
This means that there is no specific HTML code provided for this test case.
3. The latest benchmark result in JSON format:
{ "RawUAString": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0", "Browser": "Firefox 71", "DevicePlatform": "Desktop", "OperatingSystem": "Ubuntu", "ExecutionsPerSecond": 4187.4033203125, "TestName": "map" }, { "RawUAString": "Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:71.0) Gecko/20100101 Firefox/71.0", "Browser": "Firefox 71", "DevicePlatform": "Desktop", "OperatingSystem": "Ubuntu", "ExecutionsPerSecond": 2736.448486328125, "TestName": "for" }
Given these inputs, I can perform the following tasks:
- Multiply each number in the array by 2 using both `map` and `for` loops.
- Compare the execution times for both methods to determine which one is faster.
To do this, I would need to implement JavaScript code that performs these calculations.
```javascript
// Assuming array is defined as follows:
const array = [9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16, 1, 4, 9, 16];
// Using map
const startTime = new Date().getTime();
array.map((value) => value * 2);
const mapTime = (new Date().getTime() - startTime) / 1000;
// Using for loop
const endTime = new Date().getTime();
for (let i = 0; i < array.length; i++) {
array[i] *= 2;
}
const forTime = (new Date().getTime() - endTime) / 1000;
console.log(`Map time: ${mapTime} seconds`);
console.log(`For loop time: ${forTime} seconds`);
if (mapTime < forTime) {
console.log("map is faster");
} else if (mapTime > forTime) {
console.log("for loop is faster");
} else {
console.log("Both methods have the same execution time");
}
When run, this code would output the execution times for both map
and for
loops. However, I don't have a specific answer to which one is faster in this case since it depends on the actual execution times of the system where this script is being executed.
