What is the value of charcodeat in JavaScript?
The charCodeAt () method returns an integer between 0 and 65535 representing the UTF-16 code unit at the given index. The UTF-16 code unit matches the Unicode code point for code points which can be represented in a single UTF-16 code unit.
How to find the charcodeat of a string?
Use the following syntax to find the character code at a particular index. index − An integer between 0 and 1 less than the length of the string; if unspecified, defaults to 0. Returns a number indicating the Unicode value of the character at the given index.
What is the definition of charcodeat in Python?
Definition and Usage. The charCodeAt() method returns the Unicode of the character at the specified index in a string. The index of the first character is 0, the second character 1, and so on.
What should the index be in charcodeat ( )?
An integer greater than or equal to 0 and less than the length of the string. If index is not a number, it defaults to 0. A number representing the UTF-16 code unit value of the character at the given index. If index is out of range, charCodeAt () returns NaN. Unicode code points range from 0 to 1114111 ( 0x10FFFF ).
When does charcodeat ( ) return Nan in JavaScript?
charCodeAt() returns NaN if the given index is less than 0 or is equal to or greater than the length of the string. Backward compatibility: In historic versions (like JavaScript 1.2) the charCodeAt() method returns a number indicating the ISO-Latin-1 codeset value of the character at the given index. The ISO-Latin-1 codeset ranges from 0 to 255.
Is there a non breaking space in ASCII character 160?
So I used charCodeAt and found it was ASCII character 160. I looked up char code 160 and saw that it is a “Non-breaking space”. You would think that a “space” character would be trimmed.
How many Unicode code points does charcodeat ( ) return?
The first 128 Unicode code points are a direct match of the ASCII character encoding. (For information on Unicode, see the JavaScript Guide .) Note: charCodeAt () will always return a value that is less than 65536.
