Leave for loop now !
Can you guess what will be the output of
let cars2 = [4,5];//cars2.length = 100;cars2.forEach((car) => { console.log(car, "some text");});,
let cars2 = []; cars2.length = 100;cars2.forEach((car) => { console.log(car, "some text");});and
let cars2 = [4,5]; cars2.length = 100;cars2.forEach((car) => { console.log(car, "some text");});I tried to create a new way of looping in JavaScript, because I liked the forEach loop and I don't like the long formate of the for loop in js. I tried to invent a new way of looping so I search for loop javascript and edited this code.
<!DOCTYPE html><html><body><h2>JavaScript For Loop</h2><p id="demo"></p><script>const cars = ["BMW", "Volvo", "Saab", "Ford", "Fiat", "Audi"];let text = "";cars.length = 100;for (let i = 0; i < cars.length; i++) { text += cars[i] + "<br>";}document.getElementById("demo").innerHTML = text;</script></body></html>This worked fine ( you can change to text += i + "<br>"; for getting counting )
the modification of array.length was working fine for the for loop.
but when I tried it with the forEach loop it's different. (a little bit obvious ) I thought I may be wrong at this but guess what even chatGPT given the wrong reply, it given the reply that I guessed at starting...
but the read results are
(Can anyone explain why?)
Isn't it interesting .
