Operators and Loops

Operators

The evaluates be by comparing value, the result will be true or false (in comparison or logical).

• We have :
  • ’==’
  • ’!=’
  • ’!==’
  • ’===’
  • ’<’
  • ’>’
  • ’<=’
  • ’>=’
• The priority of parentheses must be observed’()’
• from left to right

  AND , OR , not

  like: (var == ‘1’ && var < ‘10’)

Loops

• It works on checking the condition if it is true entry into the block.
• type of loops:
  • for
  • while
  • do while

for

• when you have a specific number of runs.
• The most common.
• The counter(var) often starts at zero.
• Every time one counter increases.
• When the condition becomes “f” out of the block.

while

• The meter usually starts with 1.
• The increase over the counter is in the block.
• Statement 1: ‘= +’ Used to add new content to var ‘msg’ every run.
• Statement 2: Increase counter variable by 1.

  Make sure not to fall into a trap of the infinity loop.🌝
