这里是显示PYRAMID但不能产生所需输出的代码。

Here is the code to display PYRAMID but its not exactly producing required output.

function generatePyramid() {
    var totalNumberofRows = 5;
    var arr = new Array();
    for (var i = 1; i <= totalNumberofRows; i++) {
        for (var j = 1; j <= i; j++) {

            arr.push(j);
            console.log(j);
        }
        console.log("\n");
    }
}

推荐答案

Try the below code

function generatePyramid() {
    var totalNumberofRows = 5;
    var output="";
    for (var i = 1; i <= totalNumberofRows; i++) {
        for (var j = 1; j <= i; j++) {
            output+=j + "     ";
        }
        console.log(output);
        output="";
    }
}
