I keep encountering this question, however my case seems to be unique as it hasn't been addressed in any of the solutions I've found on SO.
My challenge involves a multidimensional array with duplicate arrays that I need to eliminate.
[
[8, 12],
[8, 17],
[8, 92],
[8, 12]
]
The array [8, 12] is repeated. How can I remove this duplicate?
Consider the following code snippet:
let array1 = [[8,12],[8,17],[8,92],[8,12]];
let array2 = new Array();
for (let i=0; i<array1.length; i++) {
let e1 = array1[i];
let exists = false;
for (let j=0; j<array2.length; j++) {
if (array2[j][0] == e1[0] && array2[j][1] == e1[1]) exists = true;
}
if (exists == false) {
array2[array2.length] = e1;
}
}
After running this code, array2 will contain unique elements from array1 without any duplicates. Although this may not be suitable for real-time game programming due to potential inefficiencies, it should still function correctly. Please note that I have not tested the code, so there may be unintended errors.
