There is also a string.slice(start, end) method, which is almost identical to string.substring(), but differs in the way it handles negative argument values. You can also get a substring from a string using the string.substr(start, length) method, which takes the number of characters to extract as its second argument. The substring() function does not alter the original string but returns the substring from the given string. If the second parameter is not specified, then the substring() method copies all characters up to the end of the string. The second optional parameter specifies the index of the first character to exclude from the returned substring.
The first parameter specifies the index of the first character from which to get the substring (in JavaScript, indexing starts from zero). Getting Substring from String in JavaScript To get a substring from a string in JavaScript, you can use the built-in string.substring(start, end) method.
