#Javascript does not equal in english alphabet how to

Now you know an easy way to compare strings. So, for comparing strings, amongst the many ways there may be, using localCompare is an effective approach because it can be used for different languages. So if you're depending on mathematical operators, getting false may be for different reasons than you believe. String1 is greater than string2 because ba n comes after ba ck.Īnd for the last example: const string1 = 'fcc'Ĭonsole.log(string1 'fcc' and 'fcc' < 'fcc' is false. String1 is not greater than string2, because h comes before w, so it is less than.įor the other example: const string1 = 'banana' You can also use mathematical operators like greater than ( >), less than ( string2)

How to Compare Strings Using Mathematical Operators So, do not depend on -1 or 1, instead on negative (less than 0) or positive (more than 0) values 2. In some browsers, instead of -1, it may return -2 or some other negative value. 'fcc' and 'Fcc' gives -1 because capital 'F' is greater than small 'f'. The comparison above gives 1 because, in the English locale, ba n in banana comes after ba c in back.Ĭonst compareValue1 = string1.localeCompare(string2)Ĭonst compareValue2 = string1.localeCompare(string3)Ĭomparing 'fcc' and 'fcc' gives 0 because they are equal in order. It gives -1 because, in the English locale, h in hello comes before w in the world (w is further down in the alphabetical order than h)Īnother example: const string1 = 'banana' Here are some examples comparing two strings: const string1 = 'hello'Ĭonst compareValue = string1.localeCompare(string2) What you had tried with if (ch > 'A' & ch < 'z') doesnt work because the range of characters in between an uppercase 'A' and a lowercase 'z' includes not only letters but some other characters that are between 'Z' and 'a'.

0 if string1 and string2 are equal in the alphabetical order.

-1 if string1 is smaller (lower in the alphabetical order) than string2.

1 if string1 is greater (higher in the alphabetical order) than string2.

Here's the syntax: string1.localeCompare(string2) You can use the localeCompare method to compare two strings in the current locale. How to Compare Strings Using localeCompare I'll show you two of them in this article.

You may want to compare two strings to know which is higher or lower alphabetically or to see if they are equal.
