Arrays

Arrays are dynamically sized in Wing and are created with the [] syntax. Individual array items can be accessed using index operation, array[index], or with the .at(index: num) method. Arrays are similar to dynamically sized arrays or vectors in other languages.

main.w

let a = MutArray<num>[1, 2, 3];

log("{a[0]}, {a[1]}, {a[2]}");

a[2] = 4;

log("mutated value: {a[2]}");
log("len: {a.length}");

let data = MutArray<num>[1, 2, 3];
let twoD = MutArray<MutArray<num>>[data];

for array in twoD {
  for item in array {
    log(item * 10);
  }
} 

Wing console output
