![]() In this implementation, we will create a simple Array of Objects in the Javascript file of Lightning Web Component and loop through it in multiple ways in LWC and Javascript. The code above will log a nicely formatted list of the groceries to the console. If you’ve spent any time around a programming language, you should have seen a for loop. forEach () will execute the same code for each element of an array. The JavaScript for loop is similar to the Java and C for loop. The forEach loop can only be used on Arrays, Sets, and Maps. while statement labeled statement break statement continue statement for.in statement for.of statement for statement A for loop repeats until a specified condition evaluates to false. So let’s just hop into the implementation. The JavaScript forEach loop is an Array method that executes a custom callback function on each item in an array. You can choose from multiple ways to loop through List. This is extremely useful especially in Javascript when you need to loop through the list to perform some operation. In this post, we will implement different ways to loop through List in LWC and Javascript. The forEach () method has a very straightforward syntax: forEach (callback (currentElement, index, arr), thisValue) As a parameter, it accepts a callback function and runs it for each entry in the array. groceries.forEach () calls the forEach method on the groceries array.forEach () takes an argument of callback function.
