How to Use Text Processing with Strings
A String
is simply a sequence of characters. There are different ways to create Strings – either as a string literal or as a String object using the String()
constructor. Strings can be compared to an array of characters and are often accessed similarly. Understanding them is crucial as they play a significant role in input and manipulation within coding.
Examples
String conversion
It's possible to use String
as a more reliable
toString()
alternative, as it works when
used on null
and undefined
. For example:
const nullVar = null; nullVar.toString(); // TypeError: nullVar is null String(nullVar); // "null" const undefinedVar = undefined; undefinedVar.toString(); // TypeError: undefinedVar is undefined String(undefinedVar); // "undefined"
