If your Windows 11 taskbar is not showing, you can try several troubleshooting steps to resolve the issue. Here are some potential solutions you can try:
In JavaScript, you can return multiple values from a function in a few different ways:
- Using an array: You can create an array with the values you want to return, and then return the array. For example:
javascriptfunction returnMultipleValues() {
let value1 = 10;
let value2 = "hello";
return [value1, value2];
}
let [returnedValue1, returnedValue2] = returnMultipleValues();
console.log(returnedValue1); // Output: 10
console.log(returnedValue2); // Output: "hello"
- Using an object: You can create an object with properties that represent the values you want to return, and then return the object. For example:
javascriptfunction returnMultipleValues() {
let value1 = 10;
let value2 = "hello";
return {value1: value1, value2: value2};
}
let {value1: returnedValue1, value2: returnedValue2} = returnMultipleValues();
console.log(returnedValue1); // Output: 10
console.log(returnedValue2); // Output: "hello"
- Using destructuring: You can return an object and then use destructuring to assign the values to variables. For example:
javascriptfunction returnMultipleValues() {
let value1 = 10;
let value2 = "hello";
return {value1: value1, value2: value2};
}
let {value1, value2} = returnMultipleValues();
console.log(value1); // Output: 10
console.log(value2); // Output: "hello"
All of these methods are valid and can be used depending on the specific use case.
