This method returns a number that could either be -1, 1, or 0. The last issue of 2022 is fully available and features 12 articles and 2 case studies. Have you tried StringComparison.Ordinal: it returns -1 because it is comparing str2 to str1, not the other way around. The strict equality operator checks for both value types of the two operands. The string1, grace, has five characters, whereas the string2, good, has four characters. Suppose you have an array of numbers named scores as in the following example. An example of such an operation is as shown below: Lastly, the localeCompare() method returns the value 0 when both strings are equal in order: In the example above, b in a bus for string2 is equal to b in a bus for string3 hence the reason why the operation returns the value 0. We often encounter situations which we have to compare strings in JavaScript programming. This refers to a string that will be compared with the reference string. The following illustrates the syntax of the compare function: The compare() function accepts two arguments a and b. WebLearn how to select two random strings from an array in Javascript and get an understanding of the logic behind it. WebWorld's simplest browser-based utility for adding symbols around letters in text. WebAlso, string.Compare (string str1, string str2) documentation says: The comparison uses the current culture to obtain culture-specific information such as casing rules and the '); } const arr1 = [21, 3, 15, 8 , 11 , 7 , 18]; const arr2 = [21, 3, Comparing strings Use the less-than and greater-than operators to compare strings: const a = "a"; const b = "b"; if (a < b) { // true console.log(`$ {a} is less than $ {b}`); } else if (a > b) { console.log(`$ {a} is greater than $ {b}`); } else { Soils and Rocks is an international scientific journal published by the Brazilian Association for Soil Mechanics and Geotechnical Engineering (ABMS) and by the Portuguese Geotechnical Society (SPG). Here, we are sorting alphabetically. If you want to compare strings based on their values and characters case, use the Strict Equality Operator (===). If you are comparing strings while basing on their length, use the length property in combination with Comparison Operators. My YT channel: youtube.com/c/deeecode, If you read this far, tweet to the author to show them you care. Consequently, you should not only depend on -1 as the only negative answer. WebThis tool sorts all input strings in alphabetical order. it returns -1 because it is comparing str2 to str1 , not the other way around. Eg, "is 48 equal to 62". No, it's less than 62 so it returns -1 To sort our things array with the localeCompare string method, we pass the localeCompare as the comparison function like so: You can call me Bruce. WebTo compare strings alphabetically, use localeCompare(). When I compare two characters in the following code, I get value True (which is correct), When I compare two one-character strings in the following code, I get value -1 which indicates that ">" is less than "0" (default culture is English), Whereas comparison of "3" and "1" (51 and 49 code values) in the following code returns 1 (as expected). You cannot reduce the number of times that comparison function is executed. Would you be able to explain (or provide reference to some documentation) how string comparison is implemented e.g. All Right Reserved. We can compare 2 strings alphabetically for sorting with the localeCompare method. Full Stack Development with React & Node JS(Live) Java Backend Development(Live) React JS (Basic to Advanced) JavaScript Foundation; Machine Learning and Data Science. You can do this in many ways.

All contributions are initially assessed by the editor. With mathematical operators, "fcc" is greater than "Fcc", but with localeCompare, "fcc".localeCompare("Fcc")" returns -1 to show that "fcc" is less than "Fcc". So, do not depend on -1 or 1, instead on negative (less than 0) or positive (more than 0) values. Soils and Rocks publishes original and innovative peer reviewed articles, technical notes, case studies, reviews and discussions in the fields of Soil and Rock Mechanics, Geotechnical Engineering, Engineering Geology and Environmental Engineering. Why I and JavaScript are printed before am? When determining which string is higher or lower alphabetically, for this case, the localeCompare() method is applied. When sort() compares two values, it sends the values to the compare function, Machado, H.M.C. It sounds like what you want is the comparison to not use culture-specific rules. Have you tried StringComparison.Ordinal: Console.WriteLine( strin Thecompare function of the sort() method accepts two arguments and returns a value that determines the sort order. JavaScript Array sort: Sorting Array Elements, // temporary array holds objects with position, // sorting the lengths array containing the lengths of, Check If an Element is in the Array: includes(), Check If Every Element Passes a Test: every(), Check If At Least One Element Passes a Test: some(), Concatenate Array Elements Into a String: join(), Removing Items from a Select Element Conditionally, First, extract the actual values into a temporaryarray using the. The following example declares three strings: string1, string2, and string3. Then we use the localeCompare() method to compare the strings based on alphabetical order.
