Substrings
Question: How do I extract a substring from a string?
Answer:
To extract a substring from a string, use the substring method:
string.substring(start,end)
Here
string
|
is the string from which you want to extract a substring.
|
start
|
is the number specifying the position of the character at which the substring begins.
(The character at start itself
will be included in the substring.)
|
end
|
is the number specifying the position of the character at which the substring ends.
(The character at end
will not be included in the substring.)
|
Note that the first character in the string corresponds to position 0,
and the last character to position string.length-1.
Examples:
'Hello'.substring(0,2) // 'He'
'Hello'.substring(0,4) // 'Hell'
