Time to become a coding champ.

Five. Variables

24/28 Variables

File1 _ script.js

// To create a variable, we use only one equals sign
// But to check if two values are equal, we use 3 equal signs.
// declare your variable here:
var myAge = 35;
console.log(myAge);

25/28 More Variable Practice
File1 _ script.js
// Declare a variable on line 3 called
// myCountry and give it a string value.
var myCountry = "Seoul";

// Use console.log to print out the length of the variable myCountry.
console.log(myCountry.length);

// Use console.log to print out the first three letters of myCountry.

console.log(myCountry.substring(0,3));

26/28 Change variable values
File1 _ script.js
// On line 2, declare a variable myName and give it your name.
var myName = "JONE STUDIO";
// On line 4, use console.log to print out the myName variable.
console.log(myName);
// On line 7, change the value of myName to be just the first 2
// letters of your name.
myName = "JO";
// On line 9, use console.log to print out the myName variable.

console.log(myName);
