No op is a term commonly used in computer programming, specifically in coding and scripting, to refer to a function or operation that has no effect or does nothing to alter the outcome. While there is no direct synonym for "no op", several alternative terms can be used interchangeably to convey the same meaning. Some possible synonyms include "null operation", "do nothing", "dummy operation", "no action", "inactive", "passive", "void operation", or "placeholder". These terms can be employed depending on the context and preference of the programmer, all conveying the concept of an operation that results in no change or effect.
