The Editor is responsible for the final decision regarding acceptance or rejection of articles. 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. For the case above, when the value of string3 is converted to lowercase, it becomes, good, which is equal to the value of string2. This sort operation uses an ordinal case-sensitive sort. When comparing strings with length greater than 1, JavaScript compares character by character. The length property in JavaScript returns the length of the specified string.
