The String substring() method

Mar 3, 2019

Learn how the JavaScript substring() method returns part of a string and how it differs from slice() by turning any negative argument into 0.

substring() returns a portion of a string and it’s similar to slice(), with some key differences.

If any parameter is negative, it is converted to 0. If any parameter is higher than the string length, it is converted to the length of the string.

So:

'This is my car'.substring(5) //'is my car'
'This is my car'.substring(5, 10) //'is my'
'This is my car'.substring(5, 200) //'is my car'
'This is my car'.substring(-6) //'This is my car'
'This is my car'.substring(-6, 2) //'Th'
'This is my car'.substring(-6, 200) //'This is my car'
