An array of related presentations

1. Creating an array

(1) Constructor

var arr=new Array()
console.log(arr)   //Array(0)

var arr=new Array(1,8,15)
console.log(arr)   //[1, 8, 15]

(2) Literals

var arr = [] 
console.log (arr)    // []

var arr = [ 1 , 8 , 15 ] 
console.log (arr)    // [1, 8, 15]

 2. bubble sort array

var arr=[58,5,65,23,25,56,16,98,34,35]
for (let j = 0; j < arr.length; j++) {
  for(let i = 0; i < arr.length; i++){
    if(arr[i]>arr[i+1]){
      var temp = arr[i];
          arr[i] = arr[i+1];
          arr[i+1] = temp;
    }
  }
  
}
console.log(arr)
