Unable to console log this from 4 to 156.

tried reviewing the concepts in the associated video somehow still lost in this.

script.js 
var number= '';

for (var i =4; i <=156; i += 1) { 
  i += 'number' + i + 'number';
} 
console.log(number + i);

First of all, you don't need a varible name = ' ' to do this challenge

2-)You are already increasing the i value in the loop decleration with this code : ( i=4 ; i<=156; i += 1). So you dont need to increase it in the function block (between {})

3-) console.log is called after the for loop which means it will log the last i variable (156) to the console. To fix this, write console.log(i) inside the for loop.

for (var i =4; i <=156; i += 1) { 
  console.log(i);
}

When using a variable, such as number in this case, you aren't supposed to put quotes around it when referencing it. The quotes make JavaScript interpret it as a string. For this exercise, however, you don't need the number variable. Just the i variable should suffice. Also, your console.log() statement should be inside the for loop, not underneath it. Try this instead:

for (var i =4; i <=156; i += 1) { 
  console.log(i);
}

I loved your explanation as well. I am truly grateful for this. I guess I still have a lot of practice and learning to go.

Basically what katherine said, this was how I wrote it.

for (var i = 4; i <= 156; i++){
   console.log(i);
}

the "i++" increment is shorthand for "i += 1" that you may see in some other languages.
