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++){
     let finalOutput = '';
     for(let j=1; j<=i; j++){
         finalOutput += j
     }
     console.log(finalOutput)
 }   
}

printNum()

output

function printNum(){
 for(let i=1; i<=4; i++){
     let finalOutput = '';
     for (let k=1; k<=4-i;k++){
         finalOutput += " "
     }
     for(let j=1; j<=i; j++){
         finalOutput += j
     }
     console.log(finalOutput)
 }
