Solution
The true answers are:
- It’s the keyword to define a variable in the local scope.
- It’s the keyword to define a variable with optionally initializing it to a value.
- It’s the keyword to define a variable that can be re-assign during the execution.
The statement "It’s the keyword to define a global variable" is not true because the 'let' keyword in JavaScript does not define a global variable, it defines a block-scoped local variable.
The statement "It’s the keyword to define a constant variable" is also not true because the 'let' keyword allows for the re-assignment of the variable. If you want to define a constant variable in JavaScript, you would use the 'const' keyword.
