loop for code example

Example 1: javascript for loop

var colors=["red","blue","green"];
for (let i = 0; i < colors.length; i++) { 
  console.log(colors[i]);
}

Example 2: for loop

for (let i = 0; i < array.length; i++) {

}

Example 3: for loop

for(int i = 0; i < some_number; i++){
  	//inside loop do whatever you want
}

Example 4: for loop

// this is javascript, but can be used in any language 
// with minor modifications of variable definitions

let array = ["foo", "bar"]

let low = 0; // the index to start at
let high = array.length; // can also be a number

/* high can be a direct access too
	the first part will be executed when the loop starts 
    	for the first time
	the second part ("i < high") is the condition 
    	for it to loop over again.
    the third part will be executen every time the code 
        block in the loop is closed.
*/ 
for(let i = low; i < high; i++) { 
  // the variable i is the index, which is
  // the amount of times the loop has looped already
  console.log(i);
  console.log(array[i]); 
} // i will be incremented when this is hit.

// output: 
/*
	0
    foo
    1
    bar
*/

Example 5: for loops

MyString = ""
for i in range(5):
  MyString += "hi"
print(MyString)

Example 6: for loop

fruits = ['apple', 'orange', 'peach']

for fruit in fruits:
  print(fruit)
