Question
Which keyword is used to declare variables in JavaScript that cannot be reassigned?
*constletvar
Solution
The keyword used to declare variables in JavaScript that cannot be reassigned is const.
When you declare a variable with const, it means that the identifier cannot be reassigned to a different value later in the code. However, it’s important to note that if the variable holds an object or an array, the contents of the object or array can still be modified, but the variable itself cannot be reassigned to a different object or array.
For example:
const myVar = 10;
myVar = 20; // This will throw an error
In summary, among the options provided (const, let, var), const is the correct choice for declaring variables that cannot be reassigned.
