Decreasing LOC while maintaining clarity with ternary and bracket notation (1st Approach - 6 LOC from Kyle Simpson's Deep JS Foundations)

ternary-bracket-notation-combo.js

/* 1st Approach - 6 LOC */

if(insertBefore) {
  workElements[adjacentWorkEntryId].before($workEntry);
}
else {
  workElements[adjacentWorkEntryId].after($workEntry);
}

/* 2nd Approach - 4 LOC (curly brace removal) */

if(insertBefore)
  workElements[adjacentWorkEntryId].before($workEntry);
else
  workElements[adjacentWorkEntryId].after($workEntry);
  
/* 3rd Approach - 2 LOC (ternary replacing if/else and bracket notation replacing repetitive code */

var method = insertBefore ? 'before' : 'after';
workElements[adjacentWorkEntryId][method]($workEntry);
