How to target all elements of a given class name in JavaScript

-
JavaScript getByClassName only targets one element by default Workarounds  "loops " Loops can mess up your code I personally don't like them. To target all elements you will have to iterate through all of them for each element you will have to add a event listener Example For instance the are 3 links of a same class and you want to add event listeners on all of them .... .... .... // JavaScript const links = document.getByClassName("links") for(var i = 0; i < links.length; i++) links[i].addEventListener('click', event => console.log(event.target.get attribute('class')))

How to evaluate a string on a regular expression rule in JavaScript

-
JavaScript has a built in regular expression function for testing if a string arguments is matching the given regular expression rule; Syntax of the regular expression tester is as follows; /regex/.test(string) Take for instance you want to test if a string contains only alphanumeric upper and lower case characters, space and numbers; const str = "Eat code sleep" /[A-Z,a-z,0-9, ]*/.test(str) // returns boolean 'true' Or in another example; const str = "Eat, Code, Sleep" /[A-Z,a-z,0-9, ]*/.test(str) // returns boolean 'false' Because commas are not included in the regular expression match rules.

How to iterate array elements using 'for loop' in JavaScript

JavaScript arrays are similar to arrays in c and in c like programming languages such as php among others In JavaScript arrays are simply collections of elements for instance Objects Numbers or other Arrays Declaring an array An array may be declared using the array constructor for instance const array = new Array() or as const array = [] Iterating an array using 'for' loop This is the implest and most common method to iterate an array is by using the 'for loop' am sure you're familiar with the syntax. take for Instance you want to iterate an array of integers and print each one of them. var ints = [1, 2, 3, 4] To iterate ints using for loop. for (var i = 0; i < ints.length; i++){         console.log(ints[i]) } // output will be // 1 // 2 // 3 // 4 In between the parentheses they are three procedures in three segments separated by colons first segment declares var i an index which gets incriminated in the third segment as long as...
