问如何使用javascript打印数组中的元素

EN

var a = ["a", "b", "c"];
a.forEach(function(entry) {
  console.log(entry);
});

var examples = ["example1", "example2", "example3"];

// You can use reduce to transform the array into result,
// appending the result of each element to the accumulated result.
var text = examples.reduce(function (result, item, index) {
    var item_number = index + 1;

    return result + " " + item_number + ". " + item;
}, "");

// You can use a variable with forEach to build up the
// result - similar to a for loop
var text = "";

examples.forEach(function (item, index) {
    var item_number = index + 1;

    text = text + " " + item_number + ". " + item;
});

// You can map each element to a new element which 
// contains the text you'd like, then join them
var text = examples.map(function (item, index) {
    var item_number = index + 1;
    return item_number + ". " + item;
}).join(" ");

// You can put them into an HTML element using document.getElementById
document.getElementById("example-text-result").innerHTML = text;

// or print them to the console (for node, or in your browser) 
// with console.log
console.log(text);

var a = ["a", "b", "c"];
a.forEach((element) => {
        console.log(element)
    }
);
