What is const in Javascript
By Tan Lee Published on Dec 18, 2024 181
`const` is a JavaScript keyword used to declare a variable whose value cannot be reassigned after initialization.
It stands for "constant," meaning the value set cannot be changed later in the code.
const pi = 3.14; console.log(pi); // Outputs: 3.14
This line would cause an error because a constant variable cannot be reassigned.
Attempting to do so results in a TypeError: Assignment to constant variable.
