Similarly, it is asked, what effect does using dashes instead of commas have here?
An em dash—inserted by typing Control+Alt+Minus between the words it separates—signals an abrupt break in thought. It can be seen as “surprising” the reader with information. If used judiciously it can mark a longer, more dramatic pause and provide more emphasis than a comma can.
Beside above, how do you use a hyphen in a sentence? Generally, you need the hyphen only if the two words are functioning together as an adjective before the noun they're describing. If the noun comes first, leave the hyphen out. This wall is load bearing. It's impossible to eat this cake because it is rock hard.
Similarly one may ask, what is the difference between a comma and a hyphen?
An em dash is most often used to indicate a pause in a sentence. It's stronger than a comma, but weaker than a period or semicolon.
What can I use instead of a dash?
Dashes can be replaced by several other punctuations including commas, colons and brackets.
