for loop html 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: js for loop
var i; //defines i
for (i = 0; i < 5; i++) { //starts loop
console.log("The Number Is: " + i); //What ever you want
}; //ends loop
//Or:
console.log("The Number Is: " + 0);
console.log("The Number Is: " + 1);
console.log("The Number Is: " + 2);
console.log("The Number Is: " + 3);
console.log("The Number Is: " + 4);
//They do the same thing!
//Hope I helped!
Example 3: javascript loop
let array = ['Item 1', 'Item 2', 'Item 3'];
array.forEach(item => {
console.log(item); // Logs each 'Item #'
});
Example 4: for i
for i = 0 to 5 then print(i)
Example 5: 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 6: for in loop javascript
let array = [1,2,3,4,5,6,7,8,9,10];
// our array that we will use the for loop on
for (let i = 0; i < array.length; i++) {
// this loop will console log the element at array[i] starting at 0
// and will continue looping for i < array.length
console.log(array[i]);
// after each loop i will increase by 1
}
// this will console log
// 1
// 2
// 3
// 4
// 5
// 6
// 7
// 8
// 9
// 10
