Here are some of the number Patterns in javascript that are mostly asked in Interview Questions.
function printNum(){
for(let i=1; i<=4; i++){
let finalOutput = '';
for(let j=1; j<=i; j++){
finalOutput += i
}
console.log(finalOutput)
}
}
printNum()
output
1
1 2
1 2 3
1 2 3 4
function printNum(){
for(let i=1; i<=4; i++){

}
printNum()
