Because a codepoint can consist of more than a single byte, the codepoint length of a string is not necessarily equal to the number of bytes used for the string.While most of the characters are represented using a single codepoint, rarely used characters from little used languages are represented using two codepoints, which simplistically means that such a character is technically a combination of two character. A codepoint length is the number of unicode codepoints that represent the value.Usage Use this property to get the codepoint length of a String object. The last character in the String object has an index of i length - 1. The length property contains an integer that indicates the number of characters in the String object. Output: enif seod yob doog yreve Remarks You can access this property in the same way as you do with all the properties. Join the elements of the array with a var str2 = arr.join( '') The length property of a JavaScript String returns the length of the string. However, you can write the reversed string to an array and then call join with the empty character, which produces a string with no separator characters. JavaScript strings are immutable and cannot be modified in place.
The following code shows how to use length. Returns the codepoint length of a String object.Ĭaution – JavaScript strings are immutable, so the length of a string cannot be modified.
