const arr = ['one', 'two', 'three', 'four', 'five'];
Step 1: Need to find the length of an array
const length = arr.length; // 5
Step 2 : Create a random Number between 0 and 1 with Math.random()
const randomNumber = Math.random();
Step 3: Multiply this random number by the length of an array to find the possible length
const possibleLength = length * randNumber;
Step 4: Round this possible Length by Math. floor
.
const rounded = Math.floor(possibleLength);
Step 5: Return the rounded in array to the generated random integer
console.log(arr(rounded));
In Simple
const findRandom = arr[Math.floor(Math.random() * arr.length)]; console.log(findRandom)
