const is a keyword introduced in ES6 Javascript.
Variables defined with const is similar to let variables, except the fact that they cannot be reassigned.

When you use the const keyword, you need to assign value to the variable during initialization.

Primitive values assigned to the constants cannot be changed.

But a constant object can change.

So const in Javascript doesn't work like constants in other objects oriented programming languages like Java or Python.

Watch the video to understand the usage of const with practical examples.
