The slice() method is a powerful tool for getting a section of an array or a string without modifying the original data. In this article, we have discussed javascript slice method. The slicedSentence variable contains the substring "lazy dog". In this example, we extracted the last 7 characters of the sentence string using a negative value for the start parameter. If we use negative values for the start and end parameters, the slice() method will extract characters from the end of the string: const sentence = "The quick brown fox jumps over the lazy dog" Ĭonst slicedSentence = sentence.slice(-7) Ĭonsole.log(slicedSentence) // "lazy dog" If we omit the end parameter, the slice() method will extract all the characters from the starting index to the end of the string: const sentence = "The quick brown fox jumps over the lazy dog" Ĭonst slicedSentence = sentence.slice(16) Ĭonsole.log(slicedSentence) // "fox jumps over the lazy dog" But I need all of these different arguments to have args.slice ().join (' '). In this example, we defined a string sentence and used the slice() method to extract a portion of the string starting from the index 10 and ending at the index 16, but not including the index 16. In the bot, there is a command where you can do a giveaway ping and the bot will send a embed with the sponsor, prize, and message. Let's take a look at an example: const sentence = "The quick brown fox jumps over the lazy dog" Ĭonst slicedSentence = sentence.slice(10, 16) We can also use the slice() method with strings. The slicedNumbers array contains the elements 3 and 4. In this example, we extracted a portion of the numbers array starting from the third element from the end (-3) and ending at the second element from the end (-1). If we use negative values for the start and end parameters, the slice() method will extract elements from the end of the array: const numbers = Ĭonst slicedNumbers = numbers.slice(-3, -1) If we omit the end parameter, the slice() method will extract all the elements from the starting index to the end of the array: const fruits = Ĭonsole.log(slicedFruits) // The console output shows that the slicedColors array contains the elements green, blue, and yellow. The extracted portion of the array was assigned to a new variable called slicedColors. We then used the slice() method to extract a part of the array starting from the index 1 and ending at the index 4, but not including the index 4. In this example, we defined an array colors with five elements. inde圎nd represents a character that's before indexStart), an empty string is returned.Const colors = Ĭonsole.log(slicedColors) // If inde圎nd More formally, in this case, the substring ends at max(inde圎nd + str.length, 0). ![]() ![]() If inde圎nd If indexStart = str.length, slice() extracts to the end of the string.If indexStart >= str.length, an empty string is returned. ![]() For example, str.slice(1, 4) extracts the second character through the fourth character (characters indexed 1, 2, and 3). Slice() extracts up to but not including inde圎nd. Changes to the text in one string do not affect the other string. Slice() extracts the text from one string and returns a new string.
