JavaScript Variables

In JavaScript, variables are used to store data. JavaScript variables are “named storage” for data. We can access the value of the variable by using variable name. We can use the variables to store different kinds of data like numbers, text, Boolean, etc.

JavaScript variables syntax:

A variable in JavaScript has a name, a value, and a memory address.

The name of the variable distinctively identifies the variable.
The value refers to data stored in the variable.
The memory address refers to the memory location of the variable.

const climate ="spring";
console.log(climate);
