JavaScript supports different kinds of loops:
for - loops through a block of code a number of times
for/in - loops through the properties of an object
for/of - loops through the values of an iterable object
while - loops through a block of code while a specified condition is true
do/while - also loops through a block of code while a specified condition is true
for (let i = 0; i < cars.length; i++) {
text += cars[i] + "<br>";
}javascript loop
//There are many loops in javascript that get the job done
let colors = ["red","blue","green"];
//More detail about loop => shorturl.at/avIRW
for(let i in colors){
console.log(colors[i])
}
//More detail about loop => shorturl.at/hBUW2
colors.forEach(color => {
console.log(color)
})
//More detail about loop => shorturl.at/pLOV6
colors.map(color => {
console.log(color)
})
//More detail about loop => shorturl.at/hlstV
for(let i = 0; i < colors.length; i++){
console.log(colors[i])
