JavaScript String length Property

Below is the example of the string length Property.

Example:

<script>  
// JavaScript to illustrate length property  
    
function func() {  
    
    // length property for string  
    document.write("GFG".length)  
}  
func();  
</script>  

Output:
```
3
```

The length property of the JavaScript object is used to find out the size of that object. This property is used with many objects like JavaScript string, JavaScript array, etc. In the case of strings, this property returns the number of characters present in the string. In the case of an array, this property returns the number of elements present in the array.

Syntax:

object.length
where the object can either be a string object or an array object

Example:

Input : print("GeeksForGeeks".length)
Output :13

Input : print([1, 2, 3, 4, 5, 6, 7, 8, 9].length)
Output :9

Explanation:
In the first example, 13 is the number of characters in the string “GeeksForGeeks”, hence the output is 13.
And likewise in the second example, the length of the array is 9 and so is the output

Program:

<script> 
// JavaScript to illustrate length property 
  
function func() { 
  
    // length property for array 
    document.write([1,2,3,4,5,6,7,8,9].length); 
    document.write("<br>"); 
  
    // length property for string 
    document.write("GeeksForGeeks".length) 
} 
func(); 
</script> 

Output:

9
13
