However, when the continue statement is executed, it behaves differently for different types of loops: In awhileloop, the condition is tested, and if it is true, the loop is executed again In afor loop, the increment expression (e.g. i++) is first evaluated, and then the condition is...
With each iteration JavaScript assigns the name of the property (a string value) to the variable item. In the example above these are:name,age, anddegree. Note thatfor-inloops also return properties and methods that are inherited through the prototype chain. An easy way to skip properties an...
Types of Loops ECMA-262, 3rd Edition, the specification that defines JavaScript’s basic syntax and behavior, defines four types of loops. The first is the standard for loop, which shares its syntax with other C-like languages: for (var i=0; i < 10; i++){ //loop body } The for ...

The for...of loop is used for iterating over iterable objects (like arrays, strings, etc.) and directly retrieves the values instead of indices. The for loop, in contrast, is more general and can be used for different types of loops, including those that iterate over indices.×...

The for...of loop is my favorite way to loop in JavaScript.It combines the conciseness of forEach loops with the ability to break.The syntax is this:const list = ['a', 'b', 'c'] for (const item of list) { console.log(item) }...

There are lots of real life examples of loops. In a grocery store when you want to buy, for example, 6 apples, you’ll repeat the action of taking an apple and putting it into your basket exactly six times. And when you get to the cash register, you’ll repeat the action of ...
Execution flow.JavaScript execution starts at the top of thescriptand proceeds sequentially. However, control structures likeloops, conditionals, and function calls can alter this flow, allowing for complex logic and behaviors. A Short History of JavaScript ...
