- The flat() method creates a new array by flattening a nested array up to the specified depth.
2. flat() Syntax

- Integer specifying how deep a nested array should be flattened. It is default value is 1
3. Example: flat() without default depth argument
- If we don't specify a depth parameter then it uses the default depth argument that is 1, so array1.flat() flattens array1 to depth 1
- If we don't specify a depth parameter then it uses the default depth argument that is 1, so array1.flat() flattens array1 to depth 1
4. Example: flat() for removing empty elements
- We can remove holes in an array that has empty slots using the flat() method.
