The String substring() method extracts characters from a string, between two positions, returning a substring, while not changing the original string.

• If start is greater than end, arguments are swapped: (7, 1) = (1, 7)
• Start or end values less than 0 are treated as 0

<!-- html element to place output -->
<p id="my_output"></p>

Example 1:

// variables
let text = 'Hello World';
let my_result = text.substring(1, 6); // starting at position 1, ending before position 6

// output to the HTML element
document.getElementById('my_output').innerHTML = my_result;

Example 2:

// variables
let text = 'Hello World';
let my_result = text.substring(5); // starting at position 5 until the end

// output to the HTML element
document.getElementById('my_output').innerHTML = my_result;

Example 1:

ello

Example 2:

World

string.substring(start, end)

Parameter	Description
start	The start position; a negative number selects from the end of the string (required)
end	The end position (not inclusive) (default is the string length)
