Major differences
w.r.t Node

The Black Hole?

SWOT Analysis

Strength, Weakness, Opportunities and Threats

Strengths

• Deno is built on RUST

• Sandbox 

• TypeScript support

• Promises in native APIs

• Code optimization will make you awestruck because of no package.json and all old school stuff. Just directly import the URL and you are good to go!

Weakness

• Doesn’t support NPM

• Standard Library + 3PL

• Slow compile time.

Opportunities

• Security.
• Command-line format for network and file access
• A very reliable framework.

('b' + 'a' + + 'a').toLowerCase()

'1' + 1

'1' - 1

= 'banana'

= '11'

= 0

Threats

• A better version of Node which fixes the security breaches
• A lot of time to reach its potential and popularity.

Why Deno?

That's something I'll leave for the audience to decide.

Once you guys try it out.

But Don't take my word for it

Hear it from the instigator himself 

Ryan's regrets about NodeJS

• Node modules
• Package JSON
• Security
• Not living up to the Promises
• Directory structure from HTML
• File Format not included in imports
• No types
• Entire vulnerable JS bundle is shipped
