Today, we will see how to communicate between the LWC components. We will cover parent to child component communication and vice versa. We will see the various ways in which we can communicate between aura components and then we will compare it with the ways available to communicate between LWC components. A side by side comparison will help to have a better understanding of how things work in LWC. Aura Components LWC Communication from the parent component to the child component 1. Passing attributes: We can pass attribute from parent component to child component. The binding between attributes can be one-way binding or two-way binding.  1.

Below is the HTML markup for the LWC component accountInfo.html <template>   <div class="slds-page-header">     <div
