//Create array
const arr = [];
for(let i = 0;i < 10;i++){
  //Fill array with random values between 1 and 50
  arr.push(Math.floor(Math.random() * 50) + 1)
}
//Display array
console.log(arr)
//Prompt user for input
const num = prompt('Enter number')
//Filter array to include only numbers that match input
const times  = arr.filter(e => e === parseInt(num))
//Print number of times
console.log(`${times.length} times`)

//It's not foolproof you can add check to confirm input is a number and all but it solves the basic problem
