loops javascript

var colors=["red","blue","green"];
for (let i = 0; i < colors.length; i++) { 
  console.log(colors[i]);
}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
*/let array = ['Item 1', 'Item 2', 'Item 3'];

// Here's 4 different ways
for (let index = 0; index < array.length; index++) {

for (let value of array) {

}

array.forEach((value, index) => {
  console.log(index); // Will log each index
  console.log(value); // Will log each value

}JS Loops
for (before loop; condition for loop; execute after loop) {
// what to do during the loop

The most common way to create a loop in Javascript
while
Sets up conditions under which a loop executes
do while
Similar to the while loop, however, it executes at least once and performs a check at the end to
see if the condition is met to execute again
break
Used to stop and exit the cycle at certain conditions
continue
Skip parts of the cycle if certain conditions are met/*Loops are great tools when you need your program to run a code block a 
certain number of times or until a condition is met, but they need a 
terminal condition that ends the looping. Infinite loops are likely to 
freeze or crash the browser, and cause general program execution mayhem, 
which no one wants.

Infinite loop example(do not call this function!):*/
function loopy() {
  while(true) {
    console.log("Hello, world!");
  }
}

/*Loop example with terminal condition:*/
function myFunc() {
  for (let i = 1; i <= 4; i += 2) {
    console.log("Still going!");
  }
}
