The JavaScript loops are used to iterate the piece of code using for, while, do while or for-in loops. It makes the code compact. It is mostly used in array. There are four types of loops in JavaScript. 1. for loop 2. while loop 3. do-while loop 4. for-in loop **For loop**
```
for (declaration ; condition ; updation [increment or decrement]){
True statement ……
} another statement
```
**Example:**\
```
for (var i = 0; i < 20; i++) {
console.log('i = '+i);
}
```
**While loop**
```
declaration
while(condition){
true statement;
updation
}
```
**Example:**
```
var i=5;
while(i<60){
console.log(i+' ');
i=i+5;
}
```
**do-while**
```
declaration
do{
true statement;
updation
} while(condition);
```
**Example:**
```
var i=5;
do{
console.log(i+' ');
i=i+5;
}while(i<60);
```
**For-in loop** The JavaScript for in statement loops through the properties of an Object.
```
for (key in object) {
code block to be executed
}
```
**Example:**
```
const person = {fname:'shivam', lname:'prajapati', age:45};
let txt = '';
for (let x in person) {
txt += person[x] + ' ';
}
console.log(txt);
```

In other words, we call the loop statement as iterable statement. JavaScript iterable statements are used to iterate a piece of code using while, while or for-in loops. It is mostly used to access the value in array. We use iterable statement because, if a line of code has to be executed multiple times, then we put that statement in the loop. by which it runs automatically In JavaScript has five types of iterable statement.
1. for loop
2. while loop
3. do-while loop
4. for-in loop
5. for-of loop
Syntax:
```
for-loop for(variable declaration; condition ; updation) statement
```
```
while loop variable declaration;while(condition){ statement; updation;}
```
```
do-while loop variable declaration;do{ statement; updation;}while(condition);
```
```
for-in loopfor( variable in objects) statement;
```
```
for-of loopfor (variable of iterable) {
statement
}
```
Example
```
JavaScript For Loop
```
