TypeScript supports arrays, similar to JavaScript. There are two ways to declare an array:
Array Methods
| Method | Description |
|---|---|
| pop() | Removes the last element of the array and return that element |
| push() | Adds new elements to the array and returns the new array length |
| sort() | Sorts all the elements of the array |
| concat() | Joins two arrays and returns the combined result |
| indexOf() | Returns the index of the first match of a value in the array (-1 if not found) |
| copyWithin() | Copies a sequence of elements within the array |
| fill() | Fills the array with a static value from the provided start index to the end index |
| shift() | Removes and returns the first element of the array |
| splice() | Adds or removes elements from the array |
| unshift() | Adds one or more elements to the beginning of the array |
| includes() | Checks whether the array contains a certain element |
| join() | Joins all elements of the array into a string |
| lastIndexOf() | Returns the last index of an element in the array |
| slice() | Extracts a section of the array and returns the new array |
| toString() | Returns a string representation of the array |
| toLocaleString() | Returns a localized string representing the array |
