Javascript: Const Global Variable

1) What is the ‘const’ keyword?

The const keyword is a way of declaring a variable as immutable. This means it can’t reassign to another value once the variable assigned. The const keyword is use in several places in JavaScript. It’s used to define global constants and local constants, declare parameters. that should not change inside a function, and display. the return values of specific tasks like Array.prototype.concat().

The const keyword is use to define a constant in JavaScript. A regular variable cannot be reassigned once it has been initialized. Who can use the const keyword to declare the data type stored in the variable Const keyword is similar to the let keyword, but it is more restrictive than let because it cannot change the value of its contents.

2) The Difference between ‘const’ and ‘let.’

In JavaScript, const is a keyword use to create constant variables. A variable declared as a const cannot reassign to another value. A variable declared with ‘let’ can reassigned. The following code snippet illustrates the difference between these two types of variables:

const PI = 3.14; //PI is a constant variable and cannot be changed
let myAge = 25; //myAge is a variable that can be changed

Constants are variables that cannot be re-assigned while they are in use. On the other hand, ‘let’ variables can reassigned later.

const PI = 3.14;
let PI = 3.14;

The const keyword in JavaScript is use to define a constant. A constant is a variable that cannot change. It can assigned only once and cannot reassign to another value. A let variable in JavaScript is also use to define a variable, but it can reassign to other matters. The difference is that the const keyword defines a constant, which means it cannot change. At the same time, the let keyword defines a variable that can change.
