Undefined, null & reference error with live example - Advance/Modern javaScript part 5
Hi Friend! in this video of advance javascript series, we are going to learn about undefined, null and reference error. The null type is one of JavaScript's primitive values along with stuff like string, number, boolean, undefined, and symbol.
A null reference represents a complete lack of identification. Simply put, if a variable is assigned to the value of null, that indicates that the variable points to no object at all.
The ReferenceError object represents an error when a non-existent variable is referenced.
