How to Get First 5 Characters from String

How to get first 5 characters from string

For single-byte strings (e.g. US-ASCII, ISO 8859 family, etc.) use substr and for multi-byte strings (e.g. UTF-8, UTF-16, etc.) use mb_substr:

// singlebyte strings
$result = substr($myStr, 0, 5);
// multibyte strings
$result = mb_substr($myStr, 0, 5);

Keep only first n characters in a string?

const result = 'Hiya how are you'.substring(0,8);
console.log(result);
console.log(result.length);

Strip all but first 5 characters - Python

A string in Python is a sequence type, like a list or a tuple. Simply grab the first 5 characters:

 some_var = 'AAAH8192375948'[:5]
 print some_var # AAAH8

The slice notation is [start:end:increment] -- numbers are optional if you want to use the defaults (start defaults to 0, end to len(my_sequence) and increment to 1). So:

 sequence = [1,2,3,4,5,6,7,8,9,10] # range(1,11)

 sequence[0:5:1] == sequence[0:5] == sequence[:5] 
 # [1, 2, 3, 4, 5]

 sequence[1:len(sequence):1] == sequence[1:len(sequence)] == sequence[1:]
 # [2, 3, 4, 5, 6, 7, 8, 9, 10]

 sequence[0:len(sequence):2] == sequence[:len(sequence):2] == sequence[::2]
 # [1, 3, 5, 7, 9]

strip removes a character or set of characters from the beginning and end of the string - entering a negative number simply means that you are attempting to remove the string representation of that negative number from the string.

How do I get only the first 5 characters of an element's text?

You probably want to take a substring of the element's textContent.

console.log(paragraphs[0].textContent.substring(0, 5));

How do I get the first n characters of a string without checking the size or going out of bounds?

Here's a neat solution:

String upToNCharacters = s.substring(0, Math.min(s.length(), n));

^{Opinion: while this solution is "neat", I think it is actually less readable than a solution that uses if / else in the obvious way. If the reader hasn't seen this trick, he/she has to think harder to understand the code. IMO, the code's meaning is more obvious in the if / else version. For a cleaner / more readable solution, see @paxdiablo's answer.}
