Question
Which ES6 feature allows for function parameters to have
default values if no value is provided during a function call?Solution
Default parameters in ES6 enable a function to use a default value for a parameter if no argument is passed. This enhances code readability and reduces the need for conditional checks. Example: function greet(name = "Guest") { Â return `Hello, ${name}!`; } console.log(greet());Â Â Â Â Â Â // Outputs: Hello, Guest! console.log(greet("Alice"));Â Â // Outputs: Hello, Alice! This feature is especially useful in scenarios where optional parameters are involved, as it simplifies function declarations. ________________________________________ Why Other Options Are Incorrect: 1. Arrow functions: Arrow functions are a concise syntax for writing functions but do not relate to parameter defaults. 2. Template literals: Template literals allow embedding expressions in strings using backticks, unrelated to parameter handling. 3. Rest parameters: Rest parameters gather multiple arguments into an array, enabling flexible argument handling but do not assign defaults. 4. Destructuring assignment: Destructuring allows unpacking values from arrays or objects but does not deal with function defaults.
