Array operations

map – Applies a mapping function to each element of an array and returns a new array with the transformed values.

For example, ["map", [1, 2, 3], ["*", ["item"], 2]] maps each element of the array [1, 2, 3] by multiplying it by 2.

filter – Filters an array based on a given condition and returns a new array containing only the elements that satisfy the condition

For example, ["filter", [1, 2, 3, 4, 5], ["==", ["%", ["item"], 2], 0]] filters the array [1, 2, 3, 4, 5] to include only the even numbers.

reduce – Reduces an array to a single value by applying a reducer function to each element and accumulating the result.

For example, ["reduce", [1, 2, 3, 4, 5], ["+", ["acc"], ["item"]], 0] reduces the array [1, 2, 3, 4, 5] to the sum of its elements.

get – Retrieves a value from an object or an array by specifying a key or index.

For example, ["get", ["item"], "name"] retrieves the value of the "name" property from the current item.

unique – Given an array returns only unique items inside this array.

For example, ["unique", [1, 2, 2]] returns [1, 2].
