let dataArray=["A1","A2","A3","A4","A5","A6","A7","A8","A9","A10"];
for (const value of dataArray){
let newArray=[];
for(i=0;i<5;i++)
{
newArray.push(value);
}
console.log(newArray)
}I am trying to push only 5 string from array but its not working as expectation as my expected output is like this
console.log(newArray);
["A1","A2","A3","A4","A5"]
I am trying to get first 5 string from dataArray and pushing them in newArray
slice method will do the job for you.
Eg: dataArray.slice(0, 5); - This will return the first 5 items from dataArray.
In your code you are iterating through the dataArray and each item in dataArray is pushed into newArray 5 times and printing it. Also in each iteration through the dataArray, the variable newArray is reinitialised.
let dataArray=["A1","A2","A3","A4","A5","A6","A7","A8","A9","A10"];
let newArr = dataArray.filter((str,index) => {
if(index < 5){
return str;
}
})
console.log(newArr)let dataArray=["A1","A2","A3","A4","A5","A6","A7","A8","A9","A10"];
let newArray=[];
for(i=0;i<5;i++)
{
newArray.push(dataArray[i]);
}
console.log(newArray);another way is .slice()
so you can do just this
let dataArray=["A1","A2","A3","A4","A5","A6","A7","A8","A9","A10"];
console.log(dataArray.slice(0,5))
