Store Multiple Values in one Variable using JavaScript Arrays
Are JavaScript arrays used to store multiple values in a single variable? JavaScript Array object allows you to store multiple values in a single variable. Values of same or different data types can be used within a JavaScript Array. JavaScript arrays use only nonnegative integers as indexes. The first element in a JavaScript array is at index 0, the second element at index 1, and so on.
How to you store multiple values in a single way? To store multiple values, there are two ways of carrying out the task. One way is to assign each value to a single variable, and the other, much more efficient way, is to assign multiple values to a single variable.
What is a var in JavaScript? var is the keyword that tells JavaScript you're declaring a variable. x is the name of that variable. = is the operator that tells JavaScript a value is coming up next. 100 is the value for the variable to store.
What is a const in JavaScript? In JavaScript, `const` means that the identifier can't be reassigned. (Not to be confused with immutable values. Unlike true immutable datatypes such as those produced by Immutable. js and Mori, a `const` object can have properties mutated.)
What is an array in JavaScript? Arrays are used to store multiple values in a single variable. This is compared to a variable that can store only one value. Each item in an array has a number attached to it, called a numeric index, that allows you to access it. In JavaScript, arrays start at index zero and can be manipulated with various methods.
The first set of examples you can perform are the following below:
var integerTypes = 22 + 2
console.log(integerTypes); and the answer is 24.
var integerTypes = 22 - 2
console.log(integerTypes); and the answer is 20.
var integerTypes = 22 * 2
console.log(integerTypes); and the answer is 44.
var integerTypes = 22 / 2
console.log(integerTypes); and the answer is 11.
The secondary set of examples you can perform are the following below:
var stringTypes = 52 + 52
console.log(stringTypes); and the answer is 104.
var stringTypes = 52 - 52
console.log(stringTypes); and the answer is 0.
var stringTypes = 52 * 52
console.log(stringTypes); and the answer is 2704.
var stringTypes = 52 / 52
console.log(stringTypes); and the answer is 1.
