Strings 3/5
Accessing Character:
We can also access different characters from a string variable, and for that, we use the square brackets []. The syntaxes for accessing characters are str.charAt(pos) and variableName(pos) where pos is the position or index of the character that we want to access and variableName is the variable to be sliced. Let’s look at an example.
123let str = 'JavaScript'; console.log(str[0] ); console.log( str.charAt(4));
