# Converting from Python to Javascript...
'''
Converting simple Python programs into equivalent Javascript programs (or vice-versa) can often be done relatively easily. Below are two equivalent programs.

    while (!front_is_clear()) {

function follow_right_wall(){

}

To convert such a simple program from Python to Javascript, one can follow the following steps. [Note that not all those steps mentioned below are applicable in the sample program listed above.]

    Replace the keyword def by function.
    Replace the colon : that indicates the beginning of a code block by {.
    Add } at the end of a code block.
    Surround conditions/test in if and while statement by parentheses (...).
    Add semi-colons ; at the end of each statement.
    Replace the keyword not by the symbol !.
    Replace the keyword and by the symbols &&.
    Replace the keyword or (not present above) by the symbols ||.
    Replace the keywords True and False by true and false.
    Replace the keyword elif by else if.
    Replace the single line comment symbol # by //
    Replace triple quotes enclosing a multi-line comment ''' ... ''' by /* ... */.
