HTML Preparation code:

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

Script Preparation code:

let data = Array(300).fill(2);
data.fill(-3, 150, 200);
const size = data.length;

Tests:

filter
for(let tick = 0; tick < 1000; tick++) { data = data.filter(element => element > 0); }
for loop slice
for(let tick = 0; tick < 1000; tick++) { for (let i = size - 1; i >= 0; --i) { if (data[i] <= 0) { data.splice(i, 1); } } }
