Angular Template Variables Stackblitz Angular has two types of variable declarations in templates: local template variables and template reference variables. angular's @let syntax allows you to define a local variable and re use it across a template, similar to the javascript let syntax. use @let to declare a variable whose value is based on the result of a template expression. There are various use cases where these template variables come in handy. for example, responding to the user input or responding to the form submission. in this article, we'll explore what are template variables and how to use them.
Template Reference Variables Template variables help you use data from one part of a template in another part of the template. use template variables to perform tasks such as respond to user input or finely tune your application's forms. Angular's @let syntax allows you to create variables directly in templates, eliminating the need for component properties for simple calculations and transformations. You can declare variables in html code by using a template element in angular 2 or ng template in angular 4 . templates have a context object whose properties can be assigned to variables using let binding syntax. What is a template reference variable? gives a local name (e.g., #box) to an element or directive instance. lets you read values or call methods directly in the template. scoped to the template where it is declared.

What are template reference variables? template reference variables (trvs) allow you to get a direct reference to an html element or angular component from the template. Template variables are a simple way to reference dom elements or directives inside your template, allowing you to use their values or manipulate them elsewhere in your component. What are template variables? template variables are variables available in the context of template. angular does not allow the developer to create a new variable in the template. instead, it allows new variables to be passed into the template through a component or directive instance. Template variables can be used within the component template, i.e.: template variables are scoped to the template that declares them. they can be applied to a dom element, a directive component, a templateref in conjunction with the ng template, and or a web component.
