By using
'==' operator we can compare values of different types.
For
example, to perform the comparison between a string, number Javascript interpreter converts String to number.
"02"
== 2 // It return true, since 02 is converted to number 2.
But in
some cases, you want strict comparison, you can do this by using === operator.
"02"
=== 2 // It return false, since we are performing strict comparison using ===
operator.
strict.html
<!DOCTYPE html> <html> <head> <title>true and false</title> </head> <body> <script type="text/javascript"> document.write("\"02\" == 2 : " + ("02" == 2) + "<br />"); document.write("\"02\" === 2 : " + ("02" === 2) + "<br />"); </script> </body> </html>
