(Javascript)β³οΈ LESSON 1: VARIABLES AND STATEMENTSπ»
> JS Variables are containers for storing information.
JavaScript statements often start with a statement identifier to identify the JavaScript action to be performed.
> JS Statement identifiers are reserved words and cannot be used as variable names (or any other things).
Eg:- break, class, const, let, for , var ,,....etc
βHOW DO WE DECLARE AND INITIALIZE iN JS?βοΈ
LET:_ The let declaration declares a block-scoped local variable, optionally initializing it to a value.
// Create a variable to store the city
let city = 'Philadelphia'// Create a variable to store the state
let state = 'Pennsylvania'// Create a variable to combine the city and state
let location = city + ', ' + state// Print the combined location to the terminal( console)
console.log(location)
Example 2:_ Let's strore numbers
// Create a number and assign to a variable
let age = 26// Add
let addResult = age + 1// 27 // Subtract
let subtractResult = age - 26.5// Multiply
let multiplyResult = age * 10// Divide
let divideResult = age / 2// -0.5 // 260 // 13 // Parenthesis can be used to make sure βοΈNote that JS comments allow you tp document your code. The content of your comment id for human only. //look the above comment lines like this Question for you??βοΈβοΈ What are the other key words used to declare variables in JS other than LET?? [
