Example 1: javascript loop through array
var data = [1, 2, 3, 4, 5, 6];
for(let i=0; i<=data.length; i++) {
console.log(data[i])
}
for(let i of data) {
console.log(i)
}
for(let i in data) {
console.log(i)
console.log(data[i])
}
data.forEach((i) => {
console.log(i)
})
data.map((i) => {
console.log(i)
})
Example 2: loop through an array javascript
let array = ['Item 1', 'Item 2', 'Item 3'];

});
_.forEach({ 'a': 1, 'b': 2 }, function(value, key) {
console.log(key)
})
function logArrayElements(element, index, array) {
console.log("a[" + index + "] = " + element)
}
[2, 5, 9].forEach(logArrayElements)
Example 6: iterate through array javascript
