💻 JS Visible Code Practice

1. Hello & Variables

document.write("

hello world

") /* hello world */ document.write(hello) var firstName; document.write('firstName') var student1 = "Saad bhai" document.write("student1 ==>"+ student1 + " " +"Mudassir") var num1 = "10" var num2 = "abc" document.write(num1 * num2) var eq = 2 + 0 + (2 - 5) * 2 document.write(eq) -4 8 4 20
Result here...

2. Alerts and Prompts

alert("hello world") document.write("hello
world") alert("hello \n world") var username; var myName = "SAAD ALI" var message; message = "hello world" alert(message) var name = "Saad" var roll = 123 var uni = "SMIU" alert(name) alert(roll) alert(uni)
Result here...

3. Table From Prompts

var noOfChilds = prompt("Enter number of childs") var partnerName = prompt("Enter partner name") var loc = prompt('Enter any location') var jobTitle = prompt('Enter job title') document.write(`
No Of Childs Partner Name Location Job Title
${noOfChilds} ${partnerName} ${loc} ${jobTitle}
`)
Result here...

4. Math & Expressions

var num1 = prompt("Enter number") var num2 = 3 document.write(num1 * num2) alert(num1 / num2) var num2 = 5 var num3 = num2+1 var num4 = num3+7 document.write(`

${num2}

`) document.write(`

${num3}

`) document.write(`

${num4}

`)
Result here...

5. Ticket & Snack Life

var ticket = 600 document.write(`the cost of 5 ticket is ${ticket * 5}`) var snack = "Lays" var age = 10 var maxAge = 85 var dailyDose = 2 var p = dailyDose * 365 var d = maxAge - age document.write(`

total snacks is ${(dailyDose * 365) * (maxAge - age) }

`) document.write(`

${p}

`) document.write(`

${d}

`)
Result here...

6. JS Variable Rules

document.getElementById('h').innerHTML = ("a. A heading stating \u201cRules for naming JS variables") document.write(`

b. Variable names can only contain Letters, Numbers, Underscores and Dollarsign. For example $my_1stVariable
d. Variable names are case Sensitive
e. Variable names should not be JS Keywords

Result here...
