JavaScript – Check if Two Strings are Equal
To check if two strings are equal in JavaScript, use equal-to operator ==
and pass the two strings as operands. The equal-to operator returns a boolean value of true if the two strings are equal, or else, it returns false.
Equal-to operator considers the case while comparing the strings. a
and A
are not equal.
Syntax
The boolean expression (or condition) to check if strings: str1 and str2 are equal, using equal-to operator is
str1 == str2
Examples
The following is a quick example to check if two strings are equal in JavaScript.
var str1 = 'hello world'; var str2 = 'hello world'; if (str1 == str2) { //strings are equal. } else { //strings are not equal. }
In the following example, we take two strings in script, and check if these two strings are equal.
index.html
Now, let us take values in the strings, such that the strings are not equal, and observe the output.
