Kalvium Lab | Create a functionality

Task:

Your task is to create a functionality which can identify whether a number is present in the given array or not. If it is present, then it should return the index of the array of that number, if not then return -1000000.

Starter code

Inside src/app.js file -> arrayOfNumbers and itemToSearch will be already given to you.

Progression 1:

create a global scoped constant NEG_INF with -1000000 value, and a function createPop

Progression 2:

add 2 variables to createPop() : currIndex, check

1. currIndex -> assign NEG_INF to this variable
2. check -> assign false to this variable

Progression 3:

create a function searchForElement. Inside this function -> check whether the given item is present in the array or not, if it is present then assign currIndex to the index at which the item is present, and give check a true value, else, if the item is not present -> keep the value of currIndex as NEG_INF and the value for check as false.

Progression 4:

In createPop(), return a function - which uses the updated values of currIndex and check (from searchForElement), in order eturn the following :

1. If the element is present in the given array -> then display -> The item is present and is at index ${currIndex}
2. Else, display --> The item is not present and is at index ${currIndex}

Happy Coding Kalvium ❤️
