How do I find locations and snippets in a folder that are similar to the specified code snippet?

[Flcwl]

Now I have a code snippet. like it:

const targetFunc = (a, b, c) => {
  return a + b  + c
}

I need find the code locations similar to function targetFunc in src. how I can do it ?

• src/a.js

const sum3 = (a, b, c) => {
  return a + b  + c
}

sum3(1, 2, 3)

• src/b.js

const sum = (a, b) => {
  return a + b
}

sum(2, 3)
