What is length and how to use it?

Answer 1

Well, that's a contextual question.
Can you tell more about it, e.g. where you see it, cause 'length" can be variable name, method name or something else. Need clarity on the context there.

Answer 2

.length can be used to find the length of an array, it's similar to python "len()" for example,

var fruits = ["apple", "guava", "strawberry"];

if (fruits.length >== 3) {
console.log("we have enough fruits");
}
else if (fruit.length > 7) {
console.log("It's too much");
}
else{
console.log("-_- wut the");
};

Answer 3

Hey there Unknown ,
Lenght can be used in many cases; it's used to find the lenght of an element (strings, array,....) :)
