Strings 4/5
Strings are Immutable:
Strings, in JavaScript, are immutable which means that their values cannot be changed once declared.
Let’s try to understand this with an example.
1234let stringVariable = 'JavaScript'; // changing the value of first character. stringVariable[0] = 'A'; console.log(stringVariable[0]);
The value did not change.
To do so, the usual practice is to create a new string variable with the value that we want to change and attach the parts of the older string to it. In this way, we can change the string,
1234let str = 'Gi'; // replacing the string G with H str = 'H' + str[1]; console.log(str);
