Problem Statement:
We are given an array consisting of different data types in JavaScript. We need to create a new array that contains the datatypes of the previous array. If the data type is a number, then we do not need to convert that number to data type, we just need to multiply it by 2, which means just double it.
For example, [45, {1:'23', 2:'46', 3:'69'}, 'string', false] => [ 90, 'object', 'string', 'boolean' ]
Code for Double the numbers in JavaScript:
myArr = [45, {1:'23', 2:'46', 3:'69'}, 'string', false];
for(let i=0; i<myArr.length; i++){
if(typeof myArr[i]==='number'){
myArr[i] = myArr[i]*2;
}
else{
myArr[i] = typeof myArr[i]
}
}
console.log(myArr)Output:
