Agenda

Role of JavaScript

• JS is the ‘brain’ of a web page
• Adds action and movement
• We can use clickable buttons and add functions to them
• We can add interactivity
• We can add alerts and pop-ups
• It has multiple data types

Introduction to Variables and the Console

Link: var, let and const for beginners (ES6)

Operators and Operands

Joining Strings

JS Console

• The JS Console is a command line interface in your browser that can execute snippets of code. To access it, do the following:
  • Settings > More tools > Developer Tool Shortcuts:
  • Mac: alt + cmd + i
  • Windows: Ctrl + Shift + i

You can see the JS execution of your website in the console and run your own JS code directly in the console.

If Statements and For Loops

Summary

• JavaScript is the brain of our website
• We can combine variables using concatenation or interpolation
• We can use the console to see what JS does behind the scenes
• We can use operators and operands to run a lot of different types of operations and use them in for loops and if statements

What I've Learned

• Try to compare a code or a description with day to day life. It makes things easier to understand and explain.
