jquery - Can javascript for loop starts from negative number? -

here standard for loop:

for (i=0; i<=5; i++) {     el.append('<span>' + + '</span>'); }

this should append 11 spans text -5 5, doesn't work @ all...

for (i=-5; i<=5; i++) {     el.append('<span>' + + '</span>'); }

is possible start i = -5, example?

during creating fiddle found misspell... i+= -5

sorry wasting time :(

yes, it's possible, , works fine.

for (i=-5; i<=5; i++) {    ... }

is same thing as

i=-5; while (i<=5) {    ... } continue {    i++ }

the point expression allowed inside for's first part.

Yet
