1. The triple equals symbol: === means equals. If two numbers are equal this is the sign.
2. Code between curly braces is called a block.

3. if 10 < 5 {
       // run some code here
   }

   This would not run the code because 10 is not less than 5.

4. Another variation of the if is the if / else.

   if (43 < 2) {
       // Run the code in here
   } else {
       // Run a different bit of code
   }      

5. Embedding variables into a a string

   Usually you can only have a string of text between it's open and closing quotes. However you can add a variable if you use backticks instead of quotes

   let name = "John";
   
   // embed a variable
   alert( `Hello, ${name}!` );
   

6. Using Replace

   Replace is a function can be used to replace any string or part of a string. Type this into the console.

   let insult = 'u fuckin wanker';
   
   insult.replace('wanker', 'arsehole');
   
   u fuckin arsehole
