When writing a for loop, the code follows this structure: for (initialization condition ending operation) `) īy default, all properties of an object are enumerable, unless they have been explicitly marked as non-enumerable using the fineProperty() method. while- loops through a block of code while a specified condition is true 5. for/of- loops through the values of an iterable object 4. for/in- loops through the properties of an object 3. for- loops through a block of code a number of times 2. It is called a for loop because it is typically used to perform an action for a specific number of times, or for each element in a collection, such as an array. JavaScript supports different kinds of loops: 1. map() - Transform each element of an array into a new value and return a new array.Ī for loop is a type of loop that is commonly used to repeat a specific set of instructions a predetermined number of times.forEach() - Iterate over the elements of an array.filter() - Create a new array with only the elements that meet certain criteria.for.of loop - For iterating over the values of an iterable object, such as an array or a string.for.in loop - A control flow statement for iterating over the properties of an object.

for loop - A control flow statement for iterating over an element of an array.
