table.Count( )

# Description

Counts the amount of keys in a table. This should only be used when a table is not numerically and sequentially indexed. For those tables, consider the length (#) operator.

If you only want to test if the table is empty or not, use table.IsEmpty instead as it is a lot faster.

# Arguments

table tbl

The table to count the keys of.

# Returns

The number of keyvalue pairs. This includes non-numeric and non-sequential keys, unlike the length (#) operator.

# Examples

## Example

There are 4 keys in this table. So it will output "4"

```local Table = { A = "1", B = "2", C = "3", D = "4" }

print( table.Count( Table ) )```

Output:

`4`

# Examples

## Example

Difference between the length (#) operator and this function.

The length (#) operator is generally considered faster, but has limitations.

```local Table = { A = "1", B = "2", C = "3", D = "4" }

print( table.Count( Table ), #Table ) -- #Table will return 0 because the table contains no numeric keys

local Table2 = { "test1", "test2", "test3" } -- 1 = "test1", 2 = "test2"

print( table.Count( Table2 ), #Table2 ) -- Both will be 3

Table2[ 5 ] = "test5" -- Insert a new value at index 5, so index 4 does not exist

-- table.Count here will return correct value, #Table2 will return 3 because
-- the new value is non sequential ( there is nothing at index 4 )
print( table.Count( Table2 ), #Table2 )```

Output:

```4 0
3 3
4 3```
