Editing Lossless compression (section)

===Executables===
{{main article|Executable compression}}
Self-extracting executables contain a compressed application and a decompressor. When executed, the decompressor transparently decompresses and runs the original application. This is especially often used in [[Demo (computer programming)|demo]] coding, where competitions are held for demos with strict size limits, as small as 1 [[kilobyte]].
This type of compression is not strictly limited to binary executables, but can also be applied to scripts, such as [[JavaScript]].
