The main problem with converting a string to lowercase is that it can result in some of the letters being changed to different characters. This can cause problems when trying to match strings or when processing data.
var str = "Hello World!"; var res = str.toLowerCase();
This code defines a string variable called str and assigns it the value “Hello World!”. It then defines a second string variable called res and assigns it the value of str converted to lowercase letters.
