the loop should go like this: 
if (digitalRead(button)) digitalWrite(led, 1)
else digitalWrite(led, 0)
delay(100) // To prevent timer issues
if (digitalRead(button)) digitalWrite(led, 1)
else digitalWrite(led, 0)
delay(100) // To prevent timer issues
(digitalWrite and if else staments should be in the same line) @Zer

yes, 'if' you want the button to decide LED state, the using 'if' is mandatory and also, 1 mean 'HIGH' and 0 means 'LOW' basically, 'if' button pressed, then turn on led (1) 'else' turn it off if and else are the absolute bare basics, you should learn them, else you might not be able to write higher programs
