How to Name Different Versions of a Function

Strategies for naming different versions of the same function to distinguish their functionality and versions clearly.

Naming different versions of the same function can be done using several strategies to clearly distinguish their functionality and versions. Here are some naming techniques:

Based on Functionality and Parameters:
- Include descriptions related to the version's functionality or parameters in the function name.
Based on Version Numbers:
- Include version numbers or descriptions in the function name to clearly distinguish different versions.
Based on Specific Applications:
- Name functions according to specific use cases or characteristics to better reflect the function's purpose.

Examples

Based on Functionality and Parameters

animateLinear
animateWithEasing
animateWithCallback

Based on Specific Applications

animatePosition
animateOpacity
animateTransform

Concrete Examples

Below are examples of naming different versions of the animate function:

Based on Functionality and Parameters:

// Linear animation function
function animateLinear({ from, to, duration, callback }) {
  const startTime = performance.now();
 
  const _run = (now) => {
    const elapsedTime = now - startTime;
    if (elapsedTime >= duration) {
      callback(to);
      cancelAnimationFrame(rid);
      return;
    }
 
    const t = elapsedTime / duration;
    const value = from + (to - from) * t;
    callback(value);
    rid = requestAnimationFrame(_run);
  };
 
  let rid = requestAnimationFrame(_run);
}
 
// Animation function with easing
function animateWithEasing({
  from,
  to,
  duration,
  callback,
  easing = (t) => t,
}) {
  const startTime = performance.now();
 
  const _run = (now) => {
    const elapsedTime = now - startTime;
    if (elapsedTime >= duration) {
      callback(to);
      cancelAnimationFrame(rid);
      return;
    }
 
    const t = elapsedTime / duration;
    const easedT = easing(t);
    const value = from + (to - from) * easedT;
    callback(value);
    rid = requestAnimationFrame(_run);
  };
 
  let rid = requestAnimationFrame(_run);
}

2.Based on Version Numbers:

// Version 1 of animate function
function animateV1(from, to, duration, callback) {
const speed = (to - from) / duration;
const startTime = Date.now();
 
const \_run = () => {
const elapsedTime = Date.now() - startTime;
if (elapsedTime >= duration) {
callback(to);
cancelAnimationFrame(rid);
return;
}
let value = from + speed \* elapsedTime;
callback(value);
requestAnimationFrame(\_run);
};
const rid = requestAnimationFrame(\_run);
}
 
// Version 2 of animate function with easing
function animateV2({ from, to, duration, callback, easing = (t) => t }) {
const startTime = performance.now();
 
const \_run = (now) => {
const elapsedTime = now - startTime;
if (elapsedTime >= duration) {
callback(to);
cancelAnimationFrame(rid);
return;
}
 
    const t = elapsedTime / duration;
    const easedT = easing(t);
    const value = from + (to - from) * easedT;
    callback(value);
    rid = requestAnimationFrame(_run);
 
};
 
let rid = requestAnimationFrame(\_run);
}

3.Based on Specific Applications:

// Animate position of an element
function animatePosition({ element, from, to, duration, easing = (t) => t }) {
  const startTime = performance.now();
 
  const _run = (now) => {
    const elapsedTime = now - startTime;
    if (elapsedTime >= duration) {
      element.style.left = to + "px";
      cancelAnimationFrame(rid);
      return;
    }
 
    const t = elapsedTime / duration;
    const easedT = easing(t);
    const value = from + (to - from) * easedT;
    element.style.left = value + "px";
    rid = requestAnimationFrame(_run);
  };
 
  let rid = requestAnimationFrame(_run);
}
 
// Animate opacity of an element
function animateOpacity({ element, from, to, duration, easing = (t) => t }) {
  const startTime = performance.now();
 
  const _run = (now) => {
    const elapsedTime = now - startTime;
    if (elapsedTime >= duration) {
      element.style.opacity = to;
      cancelAnimationFrame(rid);
      return;
    }
 
    const t = elapsedTime / duration;
    const easedT = easing(t);
    const value = from + (to - from) * easedT;
    element.style.opacity = value;
    rid = requestAnimationFrame(_run);
  };
 
  let rid = requestAnimationFrame(_run);
}

By using descriptive names based on functionality, versioning, or specific applications, you can clearly distinguish between different versions of the same-named functions. This approach improves code readability and maintainability, making it easier to understand and use the functions in various contexts.
