I'm creating a site and i needed to do some js. I'm not that good with it but tought i would figer it out. Not. I created a for loop but it does not run.
function order(user,product){
var index;
for(var i = 0; i<users.lenght; i++){
if(user == users[i]){
index = i;
break;
}
}
var budget = budgets[index];
alert(budget);
}
the creation of the users and budgets arrays are done with php and after checking with alert() it was how it should be.
Can anyone help me please?
lenght is spelt length. The misspelt property does not exist, so it undefined, which is equivalent to 0.

This is my code but when i run this code in console always giving me Congratulations.
Help me for solve this problem.
var val=Math.floor(Math.random() * 10) + 1;
console.log(val);
var Predict = Number(prompt("Prediction ?"));
for(var i=1 ; i <= 3; i++){
if(Predict<val){console.log("Up")};
if(Predict=val){console.log("Congratulations") };
if(Predict>val){console.log("Down")}
}
Equal operator assigns the right hand to the left hand and so the result is always true! To compare two values use double equals like this:
if (Predict==val){console.log("Congratulations") };

Hi im pretty sure what im about to post might not be enough info (if so please let me know what more is needed). I am using node js and having a really weird error. Below is the code and output.
if (currentPrice > variableData[i].stopLossHard) {
console.log('if')
console.log(currentPrice)
console.log('is more than')
console.log(variableData[i].stoplossHard)
}
Output:
if
92.7
is more than
93.62700000000001
This is consistently happening. I also made sure that both currentPrice and variableData[i].stopLossHard are numbers and not strings (I made sure in the code and in the output its the color of a number not a string)
Any ideas is highly appreciated.
The attribute you print is different than the one you check in the if statement:
(In the if stopLossHard has a capital L, stop-L-ossHard, what you print doesn't)
Try this:
if (currentPrice > variableData[i].stoplossHard) {
console.log('if')
console.log(currentPrice)
console.log('is more than')
console.log(variableData[i].stoplossHard)
}

I am doing a coding challenge where the letters in a string are replaced by their partner letters, I know that there is probably a better way to do this, but I just want to know why this doesn't work. Here is the code:
function DNAStrand(dna){
var strObject = {"A":"T", "T":"A", "C":"G", "G":"C"};
let newDna = "";
for (let i=0; i < dna.lenght; i++){
newDna += strObject[dna[i]];
}
return newDna
}
the function returns an empty string or "", the value of newDna before the loop, it doesn't change.
for (let i=0; i < dna.lenght; i++){
You made a typo. Change this to dna.length.

I'm trying to take a string and check whether or not it contains a lowercase letter or number, and then if so push that letter or number to an array.
for(let i = 0; i < datearg.length; i++)
{
log.info(datearg.charAt(i));
if(/[a-z]/.test(datearg.charAt(i))) letter_num++; letters.push(datearg.charAt(i));
if(/[0-9]/.test(datearg.charAt(i))) number_num++; numbers.push(datearg.charAt(i));
}
However, both if statements always evaluate to true and the arrays end up containing every single character in datearg. Anyone know why?
if(/[a-z]/.test(datearg.charAt(i))) letter_num++; letters.push(datearg.charAt(i));
is equivalent to
if(/[a-z]/.test(datearg.charAt(i))) { letter_num++; }
letters.push(datearg.charAt(i));
i.e. push is not conditional. This is the primary reason why many style guides heavily discourage control structures without braces (which only take a single statement).

I'm trying to get the console to read "No goal!" but every time I run it, I get "Goal". I'm guessing there's some basic syntax error that I'm making?
let isSoccerFan = false;
if (isSoccerFan=true) {
console.log("Goal!");
} else{
console.log("No goal!")
}
Your code is not correct. Try this:
let isSoccerFan = false;
if (isSoccerFan) {
console.log('Goal!');
} else {
console.log('No goal!');
}
