Great work you now know the fundamentals of using Handlebars! Let’s recap a few key points:

• Handlebars is an external library used to create templates which are a mix of HTML, text, and expressions.
• Handlebars uses expressions which are wrapped inside double braces like: {{someVariable}}
• A script tag with a type of "text/x-handlebars-template" is used to deliver a template to the browser.
• Handlebar.compile() returns a templating function from a template script intended for Handlebars.
• A template created from .compile() will take an object as an argument and use it as context to generate a string containing HTML.
• Handlebars has built in block helpers which can be included in a Handlebars script.
• Block helpers have a starting expression and an ending expression. The starting expression will have a # appears before a keyword. The ending expression will have the same keyword but with a / character to denote the end.
• The {{if}} will conditionally render a block of code.
• An {{else}} expression can be inserted into an if helper block and used as part of the conditional statement.
• {{each}} is another built-in helper expression which accepts an an array to iterate through.
• In the block helper functions, the {{this}} expression gives context and serves as a placeholder for the current value.
