this question has answer here: what's difference between using “let” , “var” declare variable? 21 answers this code logs 6 , 6 times: (function timer() { (var i=0; i<=5; i++) { settimeout(function clog() {console.log(i)}, i*1000); } })(); but code... (function timer() { (let i=0; i<=5; i++) { settimeout(function clog() {console.log(i)}, i*1000); } })(); ... logs following result: 0 1 2 3 4 5 why? is because let binds inner scope each item differently , var keeps latest value of i ? with var have function scope, , 1 shared binding of loop iterations - i.e. i in every settimeout callback means the same variable finally equal 6 after loop iteration ends. with let have block scope , when used in for loop new binding each iteration - i.e. i in every settimeout callback means a different va...

i need highlight text in html, given start , end position (integers, example 600th 712th character). i able using range.setstart(startnode, startoffset) , range.setend(endnode, endoffset) , works if know startnode , endnode , textnodes , inside shallow element. is possible highlight text without knowing these nodes ? if not, optimal solution determine start , end nodes ? 1 solution go through dom , count characters... you can use treewalker textnodes main div , go through textcontent's length determine start , end points should : var maindiv = document.getelementbyid('main'); // create treewalker accept textnodes var treewalker = document.createtreewalker(maindiv,nodefilter.show_text,null,false); // array containing our textnodes var textnodelist = []; while(treewalker.nextnode()) textnodelist.push(treewalker.currentnode); function getrangefromint(start, end){ var indexsizeerror = 'indexsizeerror: index or size negative or greater...
