In this JavScript tutorial i will discuss about JavaScript map() function. The JavaScript map() method create a new array with the result of calling a provided function on every element in the calling array.
Map() calls a provided callback function once for each element in an array and return a new array from the result. If you don't understand the above quote then see the JavaScript map syntex.
See the below example of JavaScript map
var arr = [10, 20, 30, 40, 50];
var newArray = arr.map(function(value, index) {
value++;
return value;
});
console.log(newArray);
If you run this code it will return
See another example of javascript map() function
var arr = [{
price: "100",
Model: "Primo"
},
{
price: "300",
Model: "A 50"
}
];
var newArray = arr.map(function(value) {
return value.price;
});
console.log(newArray);
Output of this code
Hope it can help you.
