Two different ways to write if statements:

1. with semicolon before then:

    if [ "Test" != 'Test' ]; then
        echo '💬'    
    else
        echo '💬'          

2. with no semicolon and new line before then

    if [ "Test" != 'Test' ] 
    then
        echo '💬'    
    else
        echo '💬'
