how to foreach in javascript code example

Example 1: javascript foreach

const avengers = ['thor', 'captain america', 'hulk'];
avengers.forEach((item, index)=>{
	console.log(index, item)
})

Example 2: javascript foreach

var colors = ['red', 'blue', 'green'];

colors.forEach(function(color) {
  console.log(color);
});

Example 3: for each js

const fruits = ['mango', 'papaya', 'pineapple', 'apple'];

// Iterate over fruits below

// Normal way
fruits.forEach(function(fruit){
  console.log('I want to eat a ' + fruit)
});

Example 4: For-each over an array in JavaScript

/** 1. Use forEach and related */
var a = ["a", "b", "c"];
a.forEach(function(entry) {
    console.log(entry);
});

/** 2. Use a simple for loop */
var index;
var a = ["a", "b", "c"];
for (index = 0; index < a.length; ++index) {
    console.log(a[index]);
}

/**3. Use for-in correctly*/
// `a` is a sparse array
var key;
var a = [];
a[0] = "a";
a[10] = "b";
a[10000] = "c";
for (key in a) {
    if (a.hasOwnProperty(key)  &&        // These checks are
        /^0$|^[1-9]\d*$/.test(key) &&    // explained
        key <= 4294967294                // below
        ) {
        console.log(a[key]);
    }
}

/** 4. Use for-of (use an iterator implicitly) (ES2015+) */
const a = ["a", "b", "c"];
for (const val of a) {
    console.log(val);
}

/** 5. Use an iterator explicitly (ES2015+) */
const a = ["a", "b", "c"];
const it = a.values();
let entry;
while (!(entry = it.next()).done) {
    console.log(entry.value);
}

Example 5: foeach in js

let colors = ['red', 'blue', 'green'];
// idx and sourceArr optional; sourceArr == colors
colors.forEach(function(color, idx, sourceArr) {
	console.log(color, idx, sourceArr)
});
// Output:
// red 0 ['red', 'blue', 'green']
// blue 1 ['red', 'blue', 'green']
// green 2 ['red', 'blue', 'green']

Example 6: foreach js

// result.params.detail = {
// "status": true,
// "message": "",
// "params": {
//     "pay_credit_remain": 115,
//     "month_expiry": "15",
//     "detail": [
//         {
//             "credit": "70",
//             "create_date": "2020-10-16",
//             "expiry_date": "2022-01-16"
//         },
//         {
//             "credit": "45",
//             "create_date": "2020-10-17",
//             "expiry_date": "2022-01-17"
//         }
//     ]
// }
//}

                 
detail = "<ul>";
result.params.detail.forEach((val) => {
  detail = detail + sprintf(lang.pay_credit_detail, val.credit, val.expiry_date);
});
detail += "</ul>";

$('#pay_credit_remain').html(detail);
