Constants

Constants were introduced in ES6(2015), and use a const keyword. Variables that are declared with const cannot be reassigned or redeclared.

Example:

const VERSION = '1.2';

📝 Task:

• [ ] Run the program mentioned below and fix the error that you see in the console. Make sure that the code result is 0.9 when it is fixed in the console.

const VERSION = '0.7';
VERSION = '0.9';
console.log(VERSION);

💡 Hints:

• Visit the Variables chapter for more info about const and also look for "TypeError assignment to constant variable" in search engines to learn a fix.
