javascript loop through array of objects using ForEach method
In es6 we have a simple loop through an array of objects in JavaScript forEach method which used us to iterate over the simple Java-Script array of objects.
let products = [ { id:1, name:"fname" }, { id:2, name:"xname" }, { id:3, name:"xname lname" } ] products.forEach((product)=>console.log(product.id,product.name)); // first iteration 1,"fname" // second iteration 2,"xname" // third iteration 3,"xname lname"
forEach methods takes the callback function parameters as an argument and runs on each object present in the array.
Second Example: using For of loop
let products = [ { id:1, name:"fname" }, { id:2, name:"xname" }, { id:3, name:"xname lname" } ] for(let product of products){ console.log(product.id,product.name) }
Here, I used a Java script for of loop therefor that on each iteration some different types of the object is assigned to the custom product variable.
