Early in the tutorial [], the core concept of arrow functions is introduced as a more concise syntax for regular JavaScript functions. The speaker highlights that traditional functions are defined using the `function` keyword, a name, parameter list, and a code block, often returning values with the `return` keyword. Arrow functions eliminate the `function` keyword and, by definition, are anonymous. Their defining characteristic, the "fat arrow" (`=>`), directly follows the parameter list and precedes the code block [], distinguishing them syntactically from their predecessors.
