In this tutorial we will show you the solution of how to compare two strings in JavaScript if condition, the task is to compare two JavaScript strings as efficiently as possible.
String comparisons in JavaScript can be used in a variety of situations, such as sorting an array of strings or determining whether or not an input string already exists in the database.

Step By Step Guide On How To Compare Two Strings In JavaScript If Condition :-
Some of the most typical operations on strings are verifying the length of a string, constructing and concatenating it with the + and += string operators, checking for the existence or location of substrings with the indexOf() function, and extracting substrings with the substring() method.
We can compare the contents of the two strings using the equal() function.
It will compare the information to check if it is comparable. It is case sensitive, but the equalsIgnoreCase() function can be used to ignore the case sensitivity.
Using compareto() function we can retrieve the difference between two strings. We can compare them lexicographically using the Unicode value of each character.
If both strings are equal, you'll get a 0 value; if one string is less than the other, you'll get a value less than 0; and vice versa.
We've used the == Operator to compare strings in an if statement.
<!DOCTYPE html>
<html>
<body>
<script>
var string1 = "TalkersCode";
var string2 = "TalkersCode";
if (string1 === string2) {
console.log("Strings matching!");
}
else {
console.log("Strings not match");
}
</script>
</body>
</html>
- To begin, type <! DOCTYPE html> to inform the web browser that the file is in HTML format.
- The < html> element, on the other hand, is used to signal the start of HTML content.
- The information about web pages is now contained in the <head> tag. This tag uses the< title> element to provide a web page title. The < head> and <title> tags, for example, are paired tags. As a result, both have the closing tags </head> and < /title>.
- Finally, the < body> element specifies the web page's content. This is where all of the stuff for the website will be written. To include our javascript code, we've added the script tag inside the body tag. We've specified two strings and given them the value TalkersCode.
- When we use the == operator to compare two strings in an if statement, we compare their reference numbers, but you'll note that it works the same way as comparing their content.
- If the strings are equal, the text string matched will be displayed; if they are not equal, Strings not matched will be displayed.
- After that, the </body> and </html> tags are used to close the body and html tags, respectively.
Conclusion :-
String comparison is simple in JavaScript, as it is in other languages. You may quickly compare two strings using the if statement, as shown above.
