return statement normally terminate function execution. But I have been realized that return statement does not work like what I expected? Where is the problem?
function SimpleSymbols() {
["a", "b", "c", "d"].forEach(function (char, index) {
try {
console.log("alert");
return "false"; //this line does not work?
} catch (err) {
}
});
}
SimpleSymbols();
forEach()
does not return. You can return from outside of the loop once the loop is completed:
function SimpleSymbols() {
var r;
["a", "b", "c", "d"].forEach(function (char, index) {
try {
console.log("alert");
r = "false"; //this line does not work?
} catch (err) {
}
});
return r
}
console.log(SimpleSymbols());
Instead you can use normal for loop:
function SimpleSymbols() {
var arr = ["a", "b", "c", "d"]
for(var i=0; i<arr.length; i++){
try {
console.log("alert");
return "false"; //this line does not work?
} catch (err) {
}
}
}
console.log(SimpleSymbols());
