Question
Question 1Variables declared using 'let' can be reassigned.
Solution
Yes, variables declared using 'let' can be reassigned. This is one of the key differences between 'let' and 'const' in JavaScript. 'let' allows you to declare a variable and change its value later in the code. Here is an example:
let myVariable = 'Hello';
console.log(myVariable); // Outputs: Hello
myVariable = 'Goodbye';
console.log(myVariable); // Outputs: Goodbye
In this example, we first declare myVariable with the value 'Hello'. We then reassign myVariable to 'Goodbye'. This is allowed because we used 'let' to declare myVariable. If we had used 'const', this would result in an error.
