let myArray : [1, 2, 3];

const myArray = {1, 2, 3};

var myArray = (1, 2, 3);

let myArray = [1, 2, 3];

A one-dimensional array is accessed using a string, while a multi-dimensional array uses numbers.

A one-dimensional array is always larger than a multi-dimensional array in size.

A one-dimensional array has a single index for access, while a multi-dimensional array uses multiple indices.

A one-dimensional array can store multiple data types, while a multi-dimensional array only stores one type.

Use array_length(array_name) to get the size.

Use len(array_name) to find the length of an array.

Call size(array_name) to determine the length.

Apply count(array_name) for the array length.

The push() method removes elements from the beginning of the array.

The push() method sorts the elements of the array in ascending order.

The purpose of the push() method in arrays is to add elements to the end of the array.

The push() method creates a new array from existing elements.

getFirst(arr)

arr.first()

arr[1]

arr[0]

String concatenation is the splitting of a single string into parts.

String concatenation is the conversion of strings to uppercase.

String concatenation is the comparison of two strings for equality.

String concatenation is the joining of two or more strings into one.

String[] array = myString.convertToArray();

String array = myString.toArray();

String[] array = myString.split("delimiter");

String[] array = myString.split();

Mutable strings are always faster than immutable strings.

Immutable strings can be modified after creation.

Mutable strings cannot be created without a specific function.

Mutable strings can be modified; immutable strings cannot be changed after creation.

Invoke the divide() method on the string.

Use the split() method on the string.

Apply the split_string() function to the string.

Use the join() method on the string.

The indexOf() method removes the first occurrence of a specified value from an array.

The indexOf() method returns the first index of a specified value in an array or string, or -1 if not found.

The indexOf() method checks if a value exists in an object and returns true or false.

The indexOf() method adds a specified value to an array or string.

Use Arrays.asList(array).contains(value);

Loop through the array and compare each element with value;

Use array.indexOf(value) to find the value;

Check if value is in array using value.equals(array);

The map() function sorts the elements of the array in ascending order.

The map() function merges two arrays into one combined array.

The purpose of the map() function in arrays is to transform each element of the array based on a given function.

The map() function filters elements of the array based on a condition.

yourString.reverse();

for(int i = 0; i < yourString.size(); i++) { yourString[i] = yourString[yourString.size() - 1 - i]; }

std::swap(yourString);

std::reverse(yourString.begin(), yourString.end());

Storing a collection of items.

Calculating mathematical equations.

for (int i = 0; i < str.length(); i++) { char c = str.charAt(i); }

foreach (char c in str) { }

for (char c : str) { }

while (str.hasNext()) { char c = str.next(); }
