FCC Calculator

this project is one of freecodecamp front-end program advanced projects which tests javascript skills and ability to find solutions when the programmer faces obstacles. In this project I used vanilla javascript as a challenge and no use of any library.

eval() function

This function saved alot of time. It calculates a string and return the results.

e.g : var x = "5+5"

eval(x) // returns 10
