To select a random value from an array in JavaScript, use the Math
object functions.
Let us say we have the following fruits array:
const fruits = [
"Apple",
"Orange",
"Mango",
"Banana",
"Cherry"
]
Now, we want to create a function that selects a random fruit from an array of fruits.
Let us write a randomValue()
function that randomly picks a value from the given list:
const randomValue = (list) => {
return list[Math.floor(Math.random() * list.length)]
}
Now you can use the above function to select a random value from an array, like below:
console.log(randomValue(fruits)) // Banana
