Text analysis can be done using "out of the box" tools or coding and scripting with the latter approach enabling scholars to explore more nuanced research questions.
Using "out of the box" tools, which don't require coding or scripting, is a good way to get started in text analysis as it will help users begin to understand possibilities and techniques. Voyant and Lexos are examples of such tools. (Mallet, used for topic modeling, is an example of a tool that requires coding but also provides users with a lot of guidance and preexisting code.)
Here is a Voyant instance that contains all of Shakespeare's plays. Stopwords like "thou" and "sir" have been applied to prevent them from dominating the results. (The selection of stopwords is part of the scholarly decision making that goes into text analysis.)

Coding is an umbrella term that involves using coding (or programming) languages to do things like create applications and websites. Scripting falls under coding and involves using coding languages to do things like automate processes and make websites more dynamic. Coding and scripting are typically done using a computer's command line or platforms like Jupiter Notebooks.
To get a sense of what coding and scripting look like in text analysis, here is a basic example from the Natural Language Toolkit, which uses the Python language. Here you can see a script being run that tags the parts of speech in the sentence, "And now for something completely different." (CC = coordinating conjunction, RB = adverb, IN = preposition, NN = noun, JJ=adjective. )
In this example from Programming Historian, you see a portion of a Python script used for counting word frequencies.
