Let me explain,x3as declared in the outer scope is used for the while comparisonx3 === 1, normally inside the while statement, I’d be able to reassignx3a new value and exit the loop. However as we’re declaring
There are numerous ways you can shorten and modify this code. For instance, instead of assigning the joined string to thestrvariable, you can reassign it to to theresvariableand then point the demo HTML document element to it i.e. res = res.join(""); document.getElementById("demo").in...
also, keep in mind that concat() doesn’t change the original array since it returns a new array. if you want to update the original array, you need to reassign the result to it. originalarray = elementstoprepend.concat(originalarray); console.log(originalarray); advantages and ...

Now, let’s reassignodysseyto its string equivalent and then usetypeofto confirm that we have successfully converted the variable’s value from a number to a string. odyssey=String(odyssey);// "2001"console.log(typeofodyssey); Copy
Notice that concat() does not actually add an item to the array, but creates a new array, which you can assign to another variable, or reassign to the original array (declaring it as let, as you cannot reassign a const):let fruits = ['banana', 'pear', 'apple'] fruits = fruits....
Before looping, we’ll usetheString.prototype.toLowerCase()methodto convert our string to all lowercase, and reassign thestrvariable. functionisUniqueString(str){str=str.toLowerCase();for(leti=0;i<str.length;i++){if(str.indexOf(str[i])!==i)returnfalse;}returntrue;} ...
As is evident from the above code snippet that now the index variable is not accessible from the outside (as the function scope does not protect it), but this doesn't generate the needed output as every time you call the function, it will reassign the index variable to 0. So every tim...
In Scala, when you declare a variable usingval, you create a read-only reference. This means that once assigned, the value cannot be changed. For example: valnumber=10 In this case,numberis a constant with a value of 10. Attempting to reassign it later in the code will lead to a com...
The benefit of object destructuring is that it allows you to reassign properties destructured from an object to another variable name. It comes in handy when renaming a lengthy property name. let user = { name: "Ifeoma Imoh", age: 100, height: 173, }; let { name: n, age: a, heigh...
