Trying to rewrite for loop, get jslint error

Question

I'm trying to combine various code so I want to declare the start of i ahead of time.

OLD

var i,
  max_i = 4;


for (i = 2; i<= max_i; i += 1)  
{
  //things
}

NEW

var i = 2,
  max_i = 4;


for (; i<= max_i; i += 1)  
{
  //things
}

The problem is that I am getting various errors in JSLint

• Expected ')' and instead saw '<='.
• Expected ';' and instead saw 'i'.
• Expected '{' and intead saw 'max_i'.

The code executes fine in both cases.

Answer 1

for (i; i<= max_i; i += 1)  
{
  //things
}
