string loop js code example

Example 1: for loop javascript

var listItem = [
        {name: 'myName1', gender: 'male'},
        {name: 'myName2', gender: 'female'},
        {name: 'myName3', gender: 'male'},
        {name: 'myName4', gender: 'female'},
      ]

    for (const iterator of listItem) {
        console.log(iterator.name+ ' and '+ iterator.gender);
    }

Example 2: for in loop javascript

function diagonalDifference(arr) {
    // Write your code here
    // return (arr); 11,2,4,4,5,6,10,8,-12
    let n = arr.length;
    let pri,sec = 0;

    pri = sec = 0; //initialize both diagonal sum to 0
    for (let i= 0; i < n; i++) {
        //console.log( "PRI(arr)= ", i,i);
        //console.log( arr[i][i]);
        //console.log( "SEC(arr)= ", i,n-i-1);
        //console.log( arr[i][n-i-1]);
        pri += arr[i][i];
        sec += arr[i][n - i - 1]; 
    }
	
  	// return |x| is the absolute value of x
    if(pri==sec){
        return (0);
    }else {
        if (pri>sec){
            return (pri-sec);
        }else{
            return (sec-pri);
        }
    }
}
