Do a Computation without Displaying Output

Evaluating an expression usually gives the result as output:

Wolfram Language code: list = Range[5]

Adding a semicolon (;) to the end of an expression suppresses the output:

Wolfram Language code: list = Range[5];

The assignment is done even though the output is suppressed:

Wolfram Language code: list
Notes

You can refer to the result of the previous computation using % even if the output is suppressed by a semicolon:

Wolfram Language code: Range[5];
Wolfram Language code: %
