Java Script Array Methods Pptx For of loops are a great choice for iterating through an array, when we only care about the elements inside of the array and not so much about the indices! with this, we can access the elements in an even more concise syntax!. Array.prototype the array.prototype is an object that allows you to define methods that all javascript arrays can inherit. it's essentially the prototype for all instances of array, and you can extend it by adding custom methods.

Arrays in javascript can be used to store multiple values in a single variable. arrays are objects with numeric indexes and various methods that can be used to modify arrays. During the last lecture we had a discussion on flow control & loops we discussed the concept of flow control using the “if” and “switch” structures and also the concept behind the “while” and “for” looping structures we also solved simple problems using flow control and loop structures if…else ? switch if the action to be taken of the value of a single variable (or a single expression), use ‘switch’ when the action depends on the values of multiple variables (or expressions), use the ‘if else’ structure compound statements at times, we need to put multiple statements at places where javascript expects only one for those situations, javascript provides a way of grouping a number of statements into a single statement, called a “statement block” this is done simply by enclosing any number of statements within curly braces, { } note: although the statements within the block end in semicolons, the block itself doesn’t for: example 1 x = 1 ; while ( x < 6000 ) { document.write ( x ) ; x = x 1 ; } for ? while when the exact number of iterations is known, use the ‘for’ loop when the number of iterations depend upon a condition being met, use the ‘while’ loop ‘for’ loops become especially useful when used in conjunction with arrays we’ll find out about arrays today, and we’ll probe their usefulness as part of ‘for’ loop structures today’s topic: arrays we will find out why we need arrays we will become able to use arrays for solving simple problems array?.

This document provides an overview of javascript arrays, including: declaring and initializing different types of arrays such as associative arrays and indexed arrays common array methods like push (), pop (), splice (), and slice () array attributes including length, indexof, and typeof techniques for adding, removing, and modifying.
